Functions

and_then

Equivalent to p.and_then(f).

any_partial_state

Returns a parser where P::PartialState is boxed. Useful as a way to avoid writing the type since it can get very large after combining a few parsers.

flat_map

Equivalent to p.flat_map(f).

look_ahead

look_ahead(p) acts as p but doesn't consume input on success.

map

Equivalent to p.map(f).

no_partial
not_followed_by

Succeeds only if parser fails. Never consumes any input.

recognize

Constructs a parser which returns the tokens parsed by parser accumulated in F: Extend<P::Input::Item> instead of P::Output.

try

try(p) behaves as p except it acts as if the parser hadn't consumed any input if p fails after consuming input.
