Struct winit::event_loop::OwnedDisplayHandle

pub struct OwnedDisplayHandle { /* private fields */ }

A proxy for the underlying display handle.

The purpose of this type is to provide a cheaply clonable handle to the underlying display handle. This is often used by graphics APIs to connect to the underlying APIs. It is difficult to keep a handle to the EventLoop type or the ActiveEventLoop type. In contrast, this type involves no lifetimes and can be persisted for as long as needed.

For all platforms, this is one of the following:

• A zero-sized type that is likely optimized out.
• A reference-counted pointer to the underlying type.

Trait Implementations

impl Clone for OwnedDisplayHandle

fn clone(&self) -> OwnedDisplayHandle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OwnedDisplayHandle

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

Formats the value using the given formatter.

impl HasDisplayHandle for OwnedDisplayHandle

fn display_handle(&self) -> Result<DisplayHandle<'_>, HandleError>

Get a handle to the display controller of the windowing system.

impl PartialEq for OwnedDisplayHandle

fn eq(&self, other: &OwnedDisplayHandle) -> 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.
