Struct WebBackend 

pub struct WebBackend { /* private fields */ }

A minimal, host-driven WASM backend.

This backend is intended to be driven by a JS host:

• push events via Self::events_mut
• advance time via Self::clock_mut
• read rendered buffers via Self::presenter_mut

Implementations

impl WebBackend

pub fn new(width: u16, height: u16) -> Self

Create a backend with an initial size.

pub fn clock_mut(&mut self) -> &mut DeterministicClock

Mutably access the clock.

pub fn events_mut(&mut self) -> &mut WebEventSource

Mutably access the event source.

pub fn presenter_mut(&mut self) -> &mut WebPresenter

Mutably access the presenter.
