InputPacket

Struct InputPacket 

Source
pub struct InputPacket {
    pub raw: RenderInput,
    pub cursor_outside_window: bool,
    pub viewport: (f32, f32),
    pub top_inset: f32,
}
Expand description

One frame’s sampled window input, taken beside the backend right after the draw (whose event pump produced it) and consumed by the input system. In serial execution it is deposited and consumed within the same tick; the pipelined driver ships it across the thread boundary instead.

Fields§

§raw: RenderInput

The raw sampled input state.

§cursor_outside_window: bool

Whether the cursor has left the window.

§viewport: (f32, f32)

Logical window size, for UI hit-testing and overlay layout.

§top_inset: f32

Window chrome overlapping the top of the render surface, in the same logical units as viewport (see RenderBackend::top_content_inset).

Implementations§

Source§

impl InputPacket

Source

pub fn sample(backend: &mut dyn RenderBackend) -> Self

Sample the backend’s accumulated input, cursor containment, and logical size into one packet. Called right after the draw so the frame’s event pump is reflected.

Source

pub fn merge_from(&mut self, newer: InputPacket)

Fold a newer packet onto this one without losing edges: one-frame pulses OR together, deltas accumulate, positions and held states take the newer value. Only needed when a consumer misses a frame (startup, a stall); steady state is one packet per tick.
