pub struct Canvas { /* private fields */ }
Expand description

An abstract structure representing a window for native applications, and a canvas for web applications.

Implementations

Open a new window, and initialize the OpenGL/WebGL context.

Run the platform-specific render loop.

Poll all events tha occurred since the last call to this method.

If double-buffering is supported, swap the buffers.

The size of the window.

The current position of the cursor, if known.

This position may not be known if, e.g., the cursor has not been moved since the window was open.

The scale factor.

Set the window title.

Set the window icon. See Window::set_icon for details.

Set the cursor grabbing behaviour.

Set the cursor position.

Toggle the cursor visibility.

Hide the window.

Show the window.

The state of a mouse button.

The state of a key.

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait. Read more

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait. Read more

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s. Read more

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s. Read more

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

Checks if self is actually part of its subset T (and can be converted to it).

Use with care! Same as self.to_subset but without any property checks. Always succeeds.

The inclusion map: converts self to the equivalent element of its superset.

The type returned in the event of a conversion error.

Performs the conversion.
