type_rules::rules

Struct And

pub struct And<T, U>(pub T, pub U);

Expand description

Rule to ensure that 2 other rules are Ok.

The rule attribute accepts multiple rules and has the same behavior but the And rule is useful for rules that accept a single rule such as All and Opt.

In case of error on both rules, the first one is returned.

§Example

use type_rules::prelude::*;

#[derive(Validator)]
struct OptionalMail(
    #[rule(Opt(And(MaxLength(1000), RegEx(r"^\S+@\S+\.\S+"))))]
    Option<String>
);
