kombi

An Iterator-based Parser Combinator Library for Rust.

Included batteries:

• Parser trait
  • Implementation for &str
  • Implementation for char
  • Implementation for <T, Iter: Iterator + Clone> Fn(Iter) -> Option<(Iter, T)>
• () to ensure that there is nothing left to parse
• Many for repeated occurrences
• Maybe for optionals (e.g. ' '.maybe() to allow, but not require, a space)
• NaturalNumber for whole numbers between 0 and u128::max_value()
• Or for choosing between two Parsers
• Then for chaining multiple Parsers together
• Transform for transforming the output of a Parser into another value.

("true".or("True"))
.or("false".or("False"))
.transform(|x|match x {
    Either::A(_) => true,
    Either::B(_) => false,
})
.parse_str("false!")? == ("!", false)
