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

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.

Returns the arity, i.e. the smallest usize not representable by the enum.

Adds a number to the enum, wrapping.

Provided Methods

Returns an iterator over the enum's values.
