Trait MappingParser

pub trait MappingParser<In, Out, NewOut, Reason = Infallible>: Sized + FnMut(In, Out) -> ParsingResult<In, NewOut, Reason> { }

A trait alias for a function that maps from the input & intermediate output to the rest of the input & a different output.

Used in Parser::map.

See match_out for a convenient way to create such a mapper.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
