bors[bot] ce694ae118 Merge #1328 ... 1328: Change TokenSource to iteration based r=matklad a=edwin0cheng This PR change the `TokenSource` trait from random access to be an iteration based trait: ```rust /// `TokenSource` abstracts the source of the tokens parser operates one. /// /// Hopefully this will allow us to treat text and token trees in the same way! pub trait TokenSource { fn current(&self) -> Token; /// Lookahead n token fn lookahead_nth(&self, n: usize) -> Token; /// bump cursor to next token fn bump(&mut self); /// Is the current token a specified keyword? fn is_keyword(&self, kw: &str) -> bool; } /// `TokenCursor` abstracts the cursor of `TokenSource` operates one. #[derive(Debug, Copy, Clone, Eq, PartialEq)] pub struct Token { /// What is the current token? pub kind: SyntaxKind, /// Is the current token joined to the next one (`> >` vs `>>`). pub is_jointed_to_next: bool, } ``` Note that the refactoring based on this new trait will be separated to incoming PRs Co-authored-by: Edwin Cheng <edwin0cheng@gmail.com>		2019-05-27 07:28:13 +00:00
