Implementations

impl<T> BasicParser<T>

where T: Grinder<Item = Option<u8>, Error = DiagBuilder2>,

pub fn new(input: Lexer<T>) -> BasicParser<T>

Create a new parser which consumes input from the given lexer.

Trait Implementations

impl<T> TokenStream<Token> for BasicParser<T>

where T: Grinder<Item = Option<u8>, Error = DiagBuilder2>,

fn peek(&mut self, offset: usize) -> Spanned<Token>

Look ahead at a token in the stream.

fn bump(&mut self)

Consume the current token.

fn consumed(&self) -> usize

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

fn last_span(&self) -> Span

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

fn emit(&mut self, diag: DiagBuilder2)

Emit a diagnostic.

fn severity(&self) -> Severity

Get the severity of the worst diagnostic emitted so far.

fn skip(&mut self)

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.

fn last_loc(&self) -> Location

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

fn is_fatal(&self) -> bool

Check whether a fatal diagnostic has been emitted.

fn is_error(&self) -> bool

Check whether an error diagnostic has been emitted.
