Trait Implementations

impl Clone for Variant

fn clone(&self) -> Self

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<T: ToVariant> From<T> for Variant

fn from(t: T) -> Self

Converts to this type from the input type.

impl PartialEq<Variant> for Variant

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl TryInto<VARIANT> for Variant

type Error = VariantConversionError

The type returned in the event of a conversion error.

fn try_into(self) -> Result<VARIANT, VariantConversionError>

Performs the conversion.

impl TryInto<Variant> for VARIANT

type Error = VariantConversionError

The type returned in the event of a conversion error.

fn try_into(self) -> Result<Variant, VariantConversionError>

Performs the conversion.

impl StructuralPartialEq for Variant
