Enum wayland_server::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 for WEnum<T>

where T: Clone,

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 for WEnum<T>

where T: Debug,

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

Formats the value using the given formatter.

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

where T: TryFrom<u32>,

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

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

impl<T> PartialEq for WEnum<T>

where T: PartialEq,

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

where T: Copy,

impl<T> Eq for WEnum<T>

where T: Eq,

impl<T> StructuralPartialEq for WEnum<T>
