Implementations

impl WgpuBackendData

pub fn new(init_info: WgpuInitInfo) -> Self

Create new backend data from initialization info

pub fn current_frame_resources(&mut self) -> &mut FrameResources

Get the current frame resources

pub fn frame_resources_at( &mut self, index: usize, ) -> Option<&mut FrameResources>

Get frame resources by index

pub fn next_frame(&mut self)

Advance to the next frame

pub fn is_initialized(&self) -> bool

Check if the backend is initialized
