Enum length

pub enum length<V> {
    bytes(V),
    chars(V),
}

Validator forwards length to inner validator.

Examples

use seventy::{
    builtins::{compare::*, string::*},
    seventy, Newtype,
};

#[seventy(validate(length::chars(le(15))))]
pub struct TextBox(String);

// Successfully constructed because the string is <= 15 characters.
assert!(TextBox::try_new("Hello, World!").is_ok());

// Unsuccessfully constructed because the string is not <= 15 characters.
assert!(TextBox::try_new("Hello, World! I am hungry.").is_err());

Variants

bytes(V)

chars(V)
