Trait TokenStream 

pub trait TokenStream {
    // Required methods
    fn advance(&mut self) -> bool;
    fn token(&self) -> &Token;
    fn token_mut(&mut self) -> &mut Token;

    // Provided methods
    fn next(&mut self) -> Option<&Token> { ... }
    fn process(&mut self, sink: &mut dyn FnMut(&Token)) { ... }
}

Consumable token stream.

Required Methods

fn advance(&mut self) -> bool

Advance to the next token.

fn token(&self) -> &Token

Access the current token.

fn token_mut(&mut self) -> &mut Token

Mutate the current token.

Provided Methods

fn next(&mut self) -> Option<&Token>

Iterate to the next token and return it.

fn process(&mut self, sink: &mut dyn FnMut(&Token))

Consume the remaining stream into the provided sink.
