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.
