Struct MaxLen 

pub struct MaxLen<const MAX: usize>;

Accepts values with at most MAX elements (inclusive).

Examples

use type_lib::rules::MaxLen;
use type_lib::Validator;

assert!(MaxLen::<5>::validate("hello").is_ok());
assert!(MaxLen::<5>::validate("too long").is_err());

Trait Implementations

impl<const MAX: usize, T: HasLength + ?Sized> Validator<T> for MaxLen<MAX>

type Error = ValidationError

The failure produced when a value violates the rule.

fn validate(value: &T) -> Result<(), Self::Error>

Checks value against the rule.
