Struct proclet::OpParserInstance

pub struct OpParserInstance<P: PunctExt, F> { /* private fields */ }

An instance for doing manual parsing of operators.

Implementations

impl<P: PunctExt, F: MatchOpFn> OpParserInstance<P, F>

pub fn clear(&mut self)

Clear the state to remove any accumulated op.

pub fn apply(&mut self, punct: P) -> Option<Result<Op<P::Span>, Error<P::Span>>>

Add a Punct to the currently accumulating op. This may return a new Op, or None if more puncts are needed. If punct has alone spacing and the accumulated op isn’t valid, it returns an error. Call OpParserInstance::finish to finish parsing.

pub fn finish(&mut self) -> Option<Result<Op<P::Span>, Error<P::Span>>>

Finish parsing the currently accumulated op.

Trait Implementations

impl<P: Clone + PunctExt, F: Clone> Clone for OpParserInstance<P, F>

where P::Span: Clone,

fn clone(&self) -> OpParserInstance<P, F>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
