Struct Host 

pub struct Host { /* private fields */ }

Configuration and callbacks for a window’s host.

Safety

This type and its methods are always safe to use.

It also brings the additional safety guarantee that all handlers given to this type will be destroyed alongside with the window.

This guarantees callbacks cannot be fired after the Window is dropped. (or after this Host object is dropped, if it never made it to a Window::create_with_host call).

Implementations

impl Host

pub fn new() -> Self

Creates a new, empty host with no callbacks.

Calling Window::create_with_host with this is equivalent to just calling Window::create.

pub fn with_main_thread(self, main_thread: impl HostMainThreadCaller) -> Self

Sets the HostMainThreadCaller handler to be used.

If another callback handler was already set, it is replaced.

Platform Compatibility notes

This is only useful on X11. On Window and macOS, this is a no-op.

pub fn with_callbacks(self, callbacks: impl HostCallbacks) -> Self

Sets the HostCallbacks handler to be used.

If another callback handler was already set, it is replaced.

Trait Implementations

impl Default for Host

fn default() -> Self

Returns the “default value” for a type.
