TokenStream extension trait with methods for appending tokens.

This trait is sealed and cannot be implemented outside of the quote crate.

Required methods

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

For use by ToTokens implementations.

Appends the token specified to this list of tokens.

fn append_all<I>(&mut self, iter: I) where
    I: IntoIterator,
    I::Item: ToTokens
[src]

For use by ToTokens implementations.

struct X;

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

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

fn append_separated<I, U>(&mut self, iter: I, op: U) where
    I: IntoIterator,
    I::Item: ToTokens,
    U: ToTokens
[src]

For use by ToTokens implementations.

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

fn append_terminated<I, U>(&mut self, iter: I, term: U) where
    I: IntoIterator,
    I::Item: ToTokens,
    U: ToTokens
[src]

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.
