Usage

/// A request to create a user.
#[derive(Validate)]
struct CreateUser {
    /// The user's username, which must be alphanumeric and between 4 and 20 characters.
    #[vate(Alphanumeric, Length::Chars(Within { min: 4, max: 32 }))]
    username: String,

    /// The user's password, which must be ASCII and greater than 8 characters long.
    #[vate(Ascii, Length::Chars(GE(8)))]
    password: String,

    /// The password confirmation, which must be equal to the password.
    #[vate(EQ(password))]
    confirm_password: String,
}
