<p>This module is the home of the [<code>Distribution</code>] trait and several of its
implementations. It is the workhorse behind some of the convenient
functionality of the [<code>Rng</code>] trait, including <a href="Rng::gen"><code>gen</code></a>, <a href="Rng::gen_range"><code>gen_range</code></a> and
of course <a href="Rng::sample"><code>sample</code></a>.</p>
<p>Abstractly, a <a href="https://en.wikipedia.org/wiki/Probability_distribution">probability distribution</a> describes the probability of
occurance of each value in its sample space.</p>
<p>More concretely, an implementation of <code>Distribution&lt;T&gt;</code> for type <code>X</code> is an
algorithm for choosing values from the sample space (a subset of <code>T</code>)
according to the distribution <code>X</code> represents, using an external source of
randomness (an RNG supplied to the <code>sample</code> function).</p>
<p>A type <code>X</code> may implement <code>Distribution&lt;T&gt;</code> for multiple types <code>T</code>.
Any type implementing [<code>Distribution</code>] is stateless (i.e. immutable),
but it may have internal parameters set at construction time (for example,
<a href="distributions::Uniform"><code>Uniform</code></a> allows specification of its sample space as a range within <code>T</code>).</p>
<h1 id="the-standard-distribution" class="section-header"><a href="#the-standard-distribution">The <code>Standard</code> distribution</a></h1>
<p>The <a href="distributions::Standard"><code>Standard</code></a> distribution is important to mention. This is the
distribution used by [<code>Rng::gen()</code>] and represents the &quot;default&quot; way to
produce a random value for many different types, including most primitive
types, tuples, arrays, and a few derived types. See the documentation of
<a href="distributions::Standard"><code>Standard</code></a> for more details.</p>
<p>Implementing <code>Distribution&lt;T&gt;</code> for <a href="distributions::Standard"><code>Standard</code></a> for user types <code>T</code> makes it
possible to generate type <code>T</code> with [<code>Rng::gen()</code>], and by extension also
with the [<code>random()</code>] function.</p>
<h1 id="distribution-to-sample-from-a-uniform-range" class="section-header"><a href="#distribution-to-sample-from-a-uniform-range">Distribution to sample from a <code>Uniform</code> range</a></h1>
<p>The <a href="distributions::Uniform"><code>Uniform</code></a> distribution is more flexible than <a href="distributions::Standard"><code>Standard</code></a>, but also
more specialised: it supports fewer target types, but allows the sample
space to be specified as an arbitrary range within its target type <code>T</code>.
Both <a href="distributions::Standard"><code>Standard</code></a> and <a href="distributions::Uniform"><code>Uniform</code></a> are in some sense uniform distributions.</p>
<p>Values may be sampled from this distribution using [<code>Rng::gen_range</code>] or
by creating a distribution object with <a href="distributions::Uniform::new"><code>Uniform::new</code></a>,
<a href="distributions::Uniform::new_inclusive"><code>Uniform::new_inclusive</code></a> or <code>From&lt;Range&gt;</code>. When the range limits are not
known at compile time it is typically faster to reuse an existing
distribution object than to call [<code>Rng::gen_range</code>].</p>
<p>User types <code>T</code> may also implement <code>Distribution&lt;T&gt;</code> for <a href="distributions::Uniform"><code>Uniform</code></a>,
although this is less straightforward than for <a href="distributions::Standard"><code>Standard</code></a> (see the
documentation in the <a href="distributions::Uniform"><code>uniform</code></a> module. Doing so enables generation of
values of type <code>T</code> with [<code>Rng::gen_range</code>].</p>
<h1 id="other-distributions" class="section-header"><a href="#other-distributions">Other distributions</a></h1>
<p>There are surprisingly many ways to uniformly generate random floats. A
range between 0 and 1 is standard, but the exact bounds (open vs closed)
and accuracy differ. In addition to the <a href="distributions::Standard"><code>Standard</code></a> distribution Rand offers
<a href="distributions::Open01"><code>Open01</code></a> and <a href="distributions::OpenClosed01"><code>OpenClosed01</code></a>. See &quot;Floating point implementation&quot; section of
<a href="distributions::Standard"><code>Standard</code></a> documentation for more details.</p>
<p><a href="distributions::Alphanumeric"><code>Alphanumeric</code></a> is a simple distribution to sample random letters and
numbers of the <code>char</code> type; in contrast <a href="distributions::Standard"><code>Standard</code></a> may sample any valid
<code>char</code>.</p>
<p><a href="distributions::WeightedIndex"><code>WeightedIndex</code></a> can be used to do weighted sampling from a set of items,
such as from an array.</p>
<h1 id="non-uniform-probability-distributions" class="section-header"><a href="#non-uniform-probability-distributions">Non-uniform probability distributions</a></h1>

<p>This gives a uniform distribution (assuming the RNG used to sample
it is itself uniform &amp; the <code>SampleRange</code> implementation for the
given type is correct), even for edge cases like <code>low = 0u8</code>,
<code>high = 170u8</code>, for which a naive modulo operation would return
numbers less than 85 with double the probability to those greater
than 85.</p>
<p>Types should attempt to sample in <code>[low, high)</code>, i.e., not
including <code>high</code>, but this may be very difficult. All the
primitive integer types satisfy this property, and the float types
normally satisfy it, but rounding may mean <code>high</code> can occur.</p>

<p>[<code>Uniform</code>] is the standard distribution to sample uniformly from a range;
e.g. <code>Uniform::new_inclusive(1, 6)</code> can sample integers from 1 to 6, like a
standard die. [<code>Rng::gen_range</code>] supports any type supported by
[<code>Uniform</code>].</p>
<p>This distribution is provided with support for several primitive types
(all integer and floating-point types) as well as [<code>std::time::Duration</code>],
and supports extension to user-defined types via a type-specific <em>back-end</em>
implementation.</p>
<p>The types <a href="crate::distributions::uniform::UniformInt"><code>UniformInt</code></a>, <a href="crate::distributions::uniform::UniformFloat"><code>UniformFloat</code></a> and <a href="crate::distributions::uniform::UniformDuration"><code>UniformDuration</code></a> are the
back-ends supporting sampling from primitive integer and floating-point
ranges as well as from [<code>std::time::Duration</code>]; these types do not normally
need to be used directly (unless implementing a derived back-end).</p>

<p>To extend [<code>Uniform</code>] to support your own types, write a back-end which
implements the <a href="crate::distributions::uniform::UniformSampler"><code>UniformSampler</code></a> trait, then implement the <a href="crate::distributions::uniform::SampleUniform"><code>SampleUniform</code></a>
helper trait to &quot;register&quot; your back-end. See the <code>MyF32</code> example below.</p>
<p>At a minimum, the back-end needs to store any parameters needed for sampling
(e.g. the target range) and implement <code>new</code>, <code>new_inclusive</code> and <code>sample</code>.
Those methods should include an assert to check the range is valid (i.e.
<code>low &lt; high</code>). The example below merely wraps another back-end.</p>
<p>The <code>new</code>, <code>new_inclusive</code> and <code>sample_single</code> functions use arguments of
type SampleBorrow<X> in order to support passing in values by reference or
by value. In the implementation of these functions, you can choose to
simply use the reference returned by <a href="crate::distributions::uniform::SampleBorrow::borrow"><code>SampleBorrow::borrow</code></a>, or you can choose
to copy or clone the value, whatever is appropriate for your type.</p>

<p>Instead of generating a float in the <code>[0, 1)</code> range using <a href="crate::distributions::Standard"><code>Standard</code></a>, the
<code>UniformFloat</code> implementation converts the output of an PRNG itself. This
way one or two steps can be optimized out.</p>
<p>The floats are first converted to a value in the <code>[1, 2)</code> interval using a
transmute-based method, and then mapped to the expected range with a
multiply and addition. Values produced this way have what equals 22 bits of
random digits for an <code>f32</code>, and 52 for an <code>f64</code>.</p>

<p>Unless you are implementing [<code>UniformSampler</code>] for your own type, this type
should not be used directly, use [<code>Uniform</code>] instead.</p>
<h1 id="implementation-notes" class="section-header"><a href="#implementation-notes">Implementation notes</a></h1>
<p>For a closed range, the number of possible numbers we should generate is
<code>range = (high - low + 1)</code>. It is not possible to end up with a uniform
distribution if we map <em>all</em> the random integers that can be generated to
this range. We have to map integers from a <code>zone</code> that is a multiple of the
range. The rest of the integers, that cause a bias, are rejected.</p>
<p>The problem with <code>range</code> is that to cover the full range of the type, it has
to store <code>unsigned_max + 1</code>, which can't be represented. But if the range
covers the full range of the type, no modulus is needed. A range of size 0
can't exist, so we use that to represent this special case. Wrapping
arithmetic even makes representing <code>unsigned_max + 1</code> as 0 simple.</p>
<p>We don't calculate <code>zone</code> directly, but first calculate the number of
integers to reject. To handle <code>unsigned_max + 1</code> not fitting in the type,
we use:
<code>ints_to_reject = (unsigned_max + 1) % range;</code>
<code>ints_to_reject = (unsigned_max - range + 1) % range;</code></p>
<p>The smallest integer PRNGs generate is <code>u32</code>. That is why for small integer
sizes (<code>i8</code>/<code>u8</code> and <code>i16</code>/<code>u16</code>) there is an optimization: don't pick the
largest zone that can fit in the small type, but pick the largest zone that
can fit in an <code>u32</code>. <code>ints_to_reject</code> is always less than half the size of
the small integer. This means the first bit of <code>zone</code> is always 1, and so
are all the other preceding bits of a larger integer. The easiest way to
grow the <code>zone</code> for the larger type is to simply sign extend it.</p>
<p>An alternative to using a modulus is widening multiply: After a widening
multiply by <code>range</code>, the result is in the high word. Then comparing the low
word against <code>zone</code> makes sure our distribution is uniform.</p>

<p>This is the most permanent failure type and implies the error cannot be

<p>This is the catch-all kind for errors from known and unknown sources
which do not have a more specific kind / handling method.</p>
<p>It is suggested to retry a couple of times or retry later when
handling; some error sources may be able to resolve themselves,
although this is not likely.</p>

<p>This error kind implies the generator needs more time or needs some
other part of the application to do something else first before it is

which require time for initialization.</p>

<h1 id="quick-start" class="section-header"><a href="#quick-start">Quick Start</a></h1>
<p>To get you started quickly, the easiest and highest-level way to get
a random value is to use [<code>random()</code>]; alternatively you can use
[<code>thread_rng()</code>]. The [<code>Rng</code>] trait provides a useful API on all RNGs, while
the [<code>distributions</code>] and [<code>seq</code>] modules provide further
functionality on top of RNGs.</p>

and jitter in memory access time.</p>
<p>This is a true random number generator, as opposed to pseudo-random
generators. Random numbers generated by <code>JitterRng</code> can be seen as fresh
entropy. A consequence is that is orders of magnitude slower than <code>OsRng</code>
and PRNGs (about 10^3 .. 10^6 slower).</p>
<p>There are very few situations where using this RNG is appropriate. Only very
few applications require true entropy. A normal PRNG can be statistically
indistinguishable, and a cryptographic PRNG should also be as impossible to
predict.</p>
<p>Use of <code>JitterRng</code> is recommended for initializing cryptographic PRNGs when
<code>OsRng</code> is not available.</p>
<p>This implementation is based on

<p>Use <code>timer_stats</code> to run the [NIST SP 800-90B Entropy Estimation Suite]
(https://github.com/usnistgov/SP800-90B_EntropyAssessment).</p>
<p>This is the recommended way to test the quality of <code>JitterRng</code>. It
should be run before using the RNG on untested hardware, after changes
that could effect how the code is optimised, and after major compiler
compiler changes, like a new LLVM version.</p>
<p>First generate two files <code>jitter_rng_var.bin</code> and <code>jitter_rng_var.min</code>.</p>
<p>Execute <code>python noniid_main.py -v jitter_rng_var.bin 8</code>, and validate it
with <code>restart.py -v jitter_rng_var.bin 8 &lt;min-entropy&gt;</code>.
This number is the expected amount of entropy that is at least available
for each round of the entropy collector. This number should be greater
than the amount estimated with <code>64 / test_timer()</code>.</p>
<p>Execute <code>python noniid_main.py -v -u 4 jitter_rng_var.bin 4</code>, and
validate it with <code>restart.py -v -u 4 jitter_rng_var.bin 4 &lt;min-entropy&gt;</code>.
This number is the expected amount of entropy that is available in the
last 4 bits of the timer delta after running noice sources. Note that
a value of 3.70 is the minimum estimated entropy for true randomness.</p>
<p>Execute <code>python noniid_main.py -v -u 4 jitter_rng_var.bin 4</code>, and
validate it with <code>restart.py -v -u 4 jitter_rng_var.bin 4 &lt;min-entropy&gt;</code>.
This number is the expected amount of entropy that is available to the
entropy collecter if both noice sources only run their minimal number of
times. This measures the absolute worst-case, and gives a lower bound
for the available entropy.</p>
