Struct EnumVariantId 

pub struct EnumVariantId(/* private fields */);

A compiler-assigned stable enum variant identifier.

Implementations

impl EnumVariantId

pub const fn new(value: u32) -> Option<Self>

Creates an identifier from its numeric representation.

pub const fn get(self) -> u32

Returns the numeric representation.

pub const fn to_be_bytes(self) -> [u8; 4]

Returns the canonical big-endian representation.

impl EnumVariantId

pub const fn first() -> Self

Returns the first value in this one-based allocation space.

pub const fn checked_next(self) -> Option<Self>

Returns the next value, or None when the allocation space is exhausted.

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,
