Trait plain_enum::TPlainEnum [−] [src]

pub trait TPlainEnum: Sized {
    const SIZE: usize;

    fn valid_usize(u: usize) -> bool;

    fn from_usize(u: usize) -> Self;

    fn checked_from_usize(u: usize) -> Option<Self>;

This trait is implemented by enums declared via the plain_enum_mod macro. Do not implement it yourself, but use this macro.

Associated Constants

Arity, i.e. the smallest usize not representable by the enum.

Required Methods

Checks whether u is the numerical representation of a valid enum value.

Converts u to the associated enum value. asserts that u is a valid value for the enum.

Converts u to the associated enum value. if u is a valid value for the enum.

Converts u to the associated enum value, but wraps u it before conversion (i.e. it applies the modulo operation with a modulus equal to the arity of the enum before converting).

Computes the difference between two enum values, wrapping around if necessary.

Converts the enum to its numerical representation.

Adds a number to the enum, wrapping.

Provided Methods

Returns an iterator over the enum's values.
