A library for parsing expressions.

It provides an interface for parsers via the Parser trait. The results of parsing are represented by the ParseResult type. A blanket implementation of Parser is provided for all functions that input a &str and return a ParseResult.

Functions that can augment parsers in various ways are also provided. For example, one_or_more takes a parser and applies it successively to the input, at least one time. combination combines applies two parsers successively and returns the results of both, provided that both of them succeed in parsing.
