Expand description
A generalized stream of tokens that accepts emission of diagnostics and tracking of the severity of issues encountered.
Required methods
Get the number of tokens consumed. Excludes tokens skipped with skip
.
fn emit(&mut self, diag: DiagBuilder2)
fn emit(&mut self, diag: DiagBuilder2)
Emit a diagnostic.
Provided methods
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.
Get the tail location of the last consumed token (bumped or skipped).
