Expand description
TokenStream is the result of the tokenization.
It consists consumable stream of Tokens.
Advance to the next token
Returns false if there are no other tokens.
Returns a reference to the current token.
Returns a mutable reference to the current token.
Helper to iterate over tokens. It
simply combines a call to .advance()
and .token().
Helper function to consume the entire TokenStream
and push the tokens to a sink function.
Returns a reference to the current token.
