ABNF

A nom-based ABNF parser.

Status

Not thoroughly tested, but "works for me" (and with arguably complex ABNFs)

Branches

There are some experimental branches. The with_generic_node branch uses an enum...

Rust enum Node { Alternation(Vec<Node>>), Concatenation(Vec<Node>>), ... }

...which may be more suitable when implementing transformations.

The master branch is a direct transformation of RFC 5234 to code.
