Struct FroxelOverflowReadbackState 

pub struct FroxelOverflowReadbackState {
    pub inflight: bool,
    pub pending_overflow_count: Option<u32>,
}

Mirror of EdgeOverflowReadbackState for the GPU light-culling per-froxel capacity auto-grow loop. The cull shader atomic-adds into LightCullingBuffers::overflow_buffer every time it bumps a froxel’s count past max_per_froxel_capacity; the host records a copy_buffer_to_buffer into the per-frame command encoder, then mapAsync’s the staging copy. When the resolved value is non-zero, the next render preamble calls crate::AwsmRenderer::set_max_per_froxel_capacity(current * 2) so subsequent frames have headroom. Single-buffered (inflight gates the next kick).

Fields

inflight: bool

true while a mapAsync is in flight against LightCullingBuffers::overflow_readback_buffer. Subsequent frames skip the copy + kick until the prior resolves.

pending_overflow_count: Option<u32>

Pending overflow_count snapshot from the most recently resolved mapAsync. Ingested at the top of the next render (set to None after reading).
