Expand description
A request to render a single frame to the provided render graph.
Fields§
§device: &'a Arc<Device>
The device this frame belongs to.
dt: f32
The elapsed seconds since the previous frame.
events: &'a [Event<()>]
A slice of events that have occurred since the previous frame.
height: u32
The height, in pixels, of the current frame.
render_graph: &'a mut RenderGraph
A render graph which rendering commands should be recorded into.
Make sure to write to swapchain_image
as part of this graph.
swapchain_image: SwapchainImageNode
A pre-bound image node for the swapchain image to be drawn.
will_exit: &'a mut bool
A mutable bool
which indicates if this frame should cause the program to exit.
width: u32
The width, in pixels, of the current frame.
window: &'a Window
A borrow of the operating system window relating to this frame.
Implementations§

impl FrameContext<'_>
sourcepub fn render_aspect_ratio(&self) -> f32
pub fn render_aspect_ratio(&self) -> f32
Returns the frame width divided by the frame height.
sourcepub fn center_cursor(&self)
pub fn center_cursor(&self)
Centers the mouse cursor within the window.
sourcepub fn set_cursor_position(&self, x: u32, y: u32)
pub fn set_cursor_position(&self, x: u32, y: u32)
Sets the mouse cursor at the specified position within the window.
