A generalized stream of tokens that accepts emission of diagnostics and tracking of the severity of issues encountered.

Required methods

pub fn peek(&mut self, offset: usize) -> Spanned<T>[src]

Look ahead at a token in the stream.

pub fn bump(&mut self)[src]

Consume the current token.

pub fn consumed(&self) -> usize[src]

Get the number of tokens consumed. Excludes tokens skipped with skip.

pub fn last_span(&self) -> Span[src]

Get the span of the last token consumed token (bumped or skipped).

pub fn emit(&mut self, diag: DiagBuilder2)[src]

Emit a diagnostic.

pub fn severity(&self) -> Severity[src]

Get the severity of the worst diagnostic emitted so far.

Provided methods

pub fn skip(&mut self)[src]

Skip the current token. Usually the same as bump, but may be used to keep skipped tokens out of the consumed tokens count by some parsers.

pub fn last_loc(&self) -> Location[src]

Get the tail location of the last consumed token (bumped or skipped).

pub fn is_fatal(&self) -> bool[src]

Check whether a fatal diagnostic has been emitted.

pub fn is_error(&self) -> bool[src]

Check whether an error diagnostic has been emitted.
