Enum wayland_client::WEnum

source · [−]

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

Expand description

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

source

impl<T> WEnum<T>

source

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.
