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.
any_send_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.
attempt	attempt(p) behaves as p except it acts as if the parser hadn't consumed any input if p fails after consuming input. (alias for try)
factory	Constructs the parser lazily on each parse_* call. This is similar to lazy but it allows different parsers to be returned on each call to p while still reporting the correct errors.
flat_map	Equivalent to p.flat_map(f).
from_str	Takes a parser that outputs a string like value (&str, String, &[u8] or Vec<u8>) and parses it using std::str::FromStr. Errors if the output of parser is not UTF-8 or if FromStr::from_str returns an error.
lazy	Constructs the parser lazily on each parse_* call. Can be used to effectively reduce the size of deeply nested parsers as only the function producing the parser is stored.
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.
opaque	Creates a parser from a function which takes a function that are given the actual parser. Though convoluted this makes it possible to hide the concrete parser type without Box or losing the full information about the parser as is the case of parser.
recognize	Constructs a parser which returns the tokens parsed by parser accumulated in F: Extend<P::Input::Item> instead of P::Output.
try	[ Deprecated ] try(p) behaves as p except it acts as if the parser hadn't consumed any input if p fails after consuming input.

FnOpaque

Alias over Opaque where the function can be a plain function pointer (does not need to capture any values)
