Struct AutoBackend 

pub struct AutoBackend(/* private fields */);

Implementations

pub fn set_preferences(preferences: &'static [Backend])

Sets which backends the AutoBackend will select from and in what order they are selected.

Default: [Win32, AppKit, Wayland, X11, Web, Android, UIKit,]

Trait Implementations

impl Backend for AutoBackend

fn instance() -> Option<&'static AutoBackend>

where AutoBackend: Sized,

This should return a reference to a static instance of the backend, as opposed to creating a new instance every time. This is because some backends may need to maintain global state. This should also return None if the backend is not implemented on the current platform.

fn is_available() -> bool

where AutoBackend: Sized,

This should be a quick check to see if the backend is available on the current platform. One should implement this with compile-time cfg checks and env var checks as necessary. Then, use cfgs to avoid compiling the methods of the backend if it is not available.

fn name(&self) -> &'static str

The name of the backend, used for logging and debugging purposes.

fn create_window( &self, settings: WindowSettings, ) -> Result<Arc<dyn BackendWindow>, RequestError>

fn list_available_monitors( &self, ) -> Result<VecDeque<Arc<dyn BackendMonitor>>, RequestError>

fn primary_monitor(&self) -> Result<Arc<dyn BackendMonitor>, RequestError>

fn backend() -> Option<&'static dyn Backend>

where Self: Sized + 'static,

Returns a reference to the instance as dyn Backend

impl Clone for AutoBackend

fn clone(&self) -> AutoBackend

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AutoBackend

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

Formats the value using the given formatter.
