Crate yarpl[−][src]

yarpl (or Yet Another Rust Parsing Library) makes use of a the Consumer struct and the Feed trait to make parsing easier.

Consumer

A Consumer tracks parsed tokens as well as some remaining unparsed input.

The Feed trait defines how a trait is parsed using a Consumer using Consumer::consume.

only	Defines a type that only parses a string.
peek	Defines a type that solely parses with `Peek`.
plan	Defines a type which parses a sequence of predefined `Feed` types.

Consumer	Holds tokens (`String`) that have been parsed, as well as remaining input.
Many	Given a type `T : Feed` and a range `n .. m`, parses `T` between `n` and `m` times.
Maybe	When parsed, always returns `Ok`. Will also construct a `Feed` object in `self` if successful.
Must	When parsed, ensures an object of type `T : Feed` is able to be parsed from a consumer, but will consume no input.
Not	A type that, when parsed, ensures an object of type `T : Feed` cannot be parsed from some `Consumer`.
Peek	Consumes a single token built from a `char` predicate.

Feed	Defines how a type may be parsed by mutating `self` and some `Consumer`.
