Struct Ascii 

pub struct Ascii;

Accepts strings whose characters are all ASCII.

An empty string passes (it has no non-ASCII characters). Combine with NonEmpty if you also require content.

Examples

use type_lib::rules::Ascii;
use type_lib::Validator;

assert!(Ascii::validate("plain-text_123").is_ok());
assert!(Ascii::validate("café").is_err());
