Struct quote::Tokens

pub struct Tokens { /* fields omitted */ }

Tokens produced by a quote! invocation.

Methods

impl Tokens

pub fn new() -> Self

Empty tokens.

pub fn append<U>(&mut self, token: U) where
    U: Into<TokenTree>, 

For use by ToTokens implementations.

Appends the token specified to this list of tokens.

pub fn append_all<T, I>(&mut self, iter: I) where
    T: ToTokens,
    I: IntoIterator<Item = T>, 

For use by ToTokens implementations.

struct X;

impl ToTokens for X {
    fn to_tokens(&self, tokens: &mut Tokens) {
        tokens.append_all(&[true, false]);
    }
}

let tokens = quote!(#X);
assert_eq!(tokens.to_string(), "true false");

pub fn append_separated<T, I, U>(&mut self, iter: I, op: U) where
    T: ToTokens,
    I: IntoIterator<Item = T>,
    U: ToTokens, 

For use by ToTokens implementations.

Appends all of the items in the iterator I, separated by the tokens U.

pub fn append_terminated<T, I, U>(&mut self, iter: I, term: U) where
    T: ToTokens,
    I: IntoIterator<Item = T>,
    U: ToTokens, 

For use by ToTokens implementations.

Appends all tokens in the iterator I, appending U after each element, including after the last element of the iterator.

Trait Implementations

impl ToTokens for Tokens

fn to_tokens(&self, dst: &mut Tokens)

impl Default for Tokens

fn default() -> Tokens

Returns the "default value" for a type.

impl Clone for Tokens

fn clone(&self) -> Tokens
