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 RFC4122 Specification (default).

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 copy 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.
