Enum Variant 

#[non_exhaustive]
#[repr(u8)]
pub enum Variant {
    NCS = 0,
    RFC4122 = 1,
    Microsoft = 2,
    Future = 3,
}

The reserved variants of UUIDs.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NCS = 0

Reserved by the NCS for backward compatibility.

RFC4122 = 1

As described in the RFC 9562 Specification (default). (for backward compatibility it is not yet renamed)

Microsoft = 2

Reserved by Microsoft for backward compatibility.

Future = 3

Reserved for future expansion.

Trait Implementations

impl Clone for Variant

fn clone(&self) -> Variant

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Variant

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Variant

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Variant

fn eq(&self, other: &Variant) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Variant

impl StructuralPartialEq for Variant

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
