PKombi - Parser combinator library in Rust

Why?

Well first of all because I can. Also because I want to understand Rust better, I want to understand how parser combinators work under the hood. Also this is quite the functional thingamabobo

Currently implemented parsers and their combinators

Parsers

• char(c): matches a single character
• digit(): matches a any ascii base 10 digit

Combinators

• skip(): skips the matched input
• maybe(): optional parse result
• or(other): first tries the self parser and if it fails then tries other
• and(other): tries to match both the self and the other parser
• then_maybe(other): optional other parser match
• many(): matches 0 or more elements
• many1(): matches atleast 1 or more elements
• choice(possibilities): matches against the provided parsers and returns the first valid match
