Enum wayland_backend::protocol::WEnum

pub enum WEnum<T> {
    Value(T),
    Unknown(u32),
}

An enum value in the protocol.

Variants

Value(T)

The interpreted value

Unknown(u32)

The stored value does not match one defined by the protocol file

Implementations

impl<T> WEnum<T>

pub fn into_result(self) -> Result<T, WEnumError>

Convert this WEnum into a result

This can be used to take advantage of the numerous helper methods on Result if you don’t plan to handle the unknown case of this enum.

You can also use the From and Into traits to perform the same conversion.

Trait Implementations

impl<T: Clone> Clone for WEnum<T>

fn clone(&self) -> WEnum<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for WEnum<T>

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

Formats the value using the given formatter.

impl<T> From<WEnum<T>> for Result<T, WEnumError>

fn from(me: WEnum<T>) -> Self

Converts to this type from the input type.

impl<T: Into<u32>> From<WEnum<T>> for u32

fn from(enu: WEnum<T>) -> u32

Converts an enum into a numerical form used by the wayland protocol.

impl<T: TryFrom<u32>> From<u32> for WEnum<T>

fn from(v: u32) -> Self

Constructs an enum from the integer format used by the wayland protocol.

impl<T: PartialEq> PartialEq for WEnum<T>

fn eq(&self, other: &WEnum<T>) -> 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.
