mail-chars

Provides lookup table based char classification for mail related grammar parts/charset, i.e. if a given char is valid in atext, ctext, dtext, token etc.

Note that this just covers grammar parts defining sets of chars (like atext, ctext, ...) but not contextual parts like e.g. quoted-pairs.

extern crate mail_chars;
use mail_chars::{Charset, rfc5322, rfc2045, CharMatchExt};

fn main() {
    assert!(Charset::AText.contains('d'));
    assert!('d'.is(Charset::AText));
    assert!('d'.is(rfc5322::AText));
    
    // `rfc*::*` are just re-exports grouped by RFC.
    assert_eq!(Charset::Token, rfc2045::Token);
    
    // If we want to test for more than on char set we can use lookup.
    let res = Charset::lookup('.');

    // This has the benefit that there is an `is_ascii` method.
    assert!(res.is_ascii());
    assert!(res.is(rfc2045::Token));
    assert!(res.is(rfc5322::CTextWs));
    assert!(!res.is(rfc5322::AText));
}
