Struct Trimmed 

pub struct Trimmed;

Accepts strings with no leading or trailing whitespace.

Useful for rejecting un-normalized input before it is stored. Whitespace is defined by char::is_whitespace via str::trim.

use type_lib::rules::Trimmed;
use type_lib::Validator;

assert!(Trimmed::validate("clean").is_ok());
assert!(Trimmed::validate(" padded ").is_err());
assert!(Trimmed::validate("trailing\n").is_err());
