Module nom_supreme::parser_ext

Extensions to the nom Parser trait which add postfix versions of the common combinators. See ParserExt for details.

Structs

AllConsuming	Parser which returns an error if the subparser didn't consume the whole input.
Complete	Parser which returns an error if the subparser returned Incomplete.
Context	Parser which attaches additional context to any errors returned by the subparser.
Cut	Parser which returns a Failure if the subparser returned an error. This prevents other branches from being tried.
Delimited	Parser which gets and discards a delimiting value both before and after the main subparser. Returns the output from the main subparser if all were successful.
FromStrParser	Parser which parses something via FromStr, using a subparser as a recognizer for the string to pass to from_str.
MapRes	Parser which runs a fallible mapping function on the output of the subparser. Any errors returned by the mapping function are transformed into a parse error.
Not	Parser which returns failure if the subparser succeeds, and succeeds if the subparser fails.
Optional	Parser which wraps the subparser output in an Option, and returns a successful None output if it fails.
Peek	Parser which runs a subparser but doesn't consume any input
Preceded	Parser which gets and discards an output from a prefix subparser before running the main subparser. Returns the output from the main subparser if both were successful.
Recognize	Parser which, when successful, discards the output of the subparser and instead returns the consumed input.
RefParser	Parser wrapping a mutable reference to a subparser.
Terminated	Parser which gets and discards an output from a second subparser, returning the output from the original parser if both were successful.
Value	Parser which, when successful, discards the output of the subparser and instead returns a clone of a value.
Verify	Parser which checks the output of its subparser against a verifier function.

Traits

ParserExt

Additional postfix parser combinators, as a complement to Parser. Mostly these are postfix versions of the combinators in nom::combinator and nom::sequence, with some additional combinators original to nom-supreme.
