Struct VertexState

struct VertexState {
    buffer: Arc<Buffer>,
    range: Range<BufferAddress>,
    is_dirty: bool,
}

The state of a single vertex buffer slot during render bundle encoding.

RenderBundleEncoder::finish uses this to drop redundant SetVertexBuffer commands from the final RenderBundle. It records one vertex buffer slot’s state changes here, and then calls this type’s flush method just before any draw command to produce a SetVertexBuffer commands if one is necessary.

Binding ranges must be validated against the size of the buffer before being stored in VertexState.

Fields

buffer: Arc<Buffer>

range: Range<BufferAddress>

is_dirty: bool

Implementations

impl VertexState

fn new(buffer: Arc<Buffer>, range: Range<BufferAddress>) -> Self

Create a new VertexState.

The range must be contained within buffer.

fn flush(&mut self, slot: u32) -> Option<ArcRenderCommand>

Generate a SetVertexBuffer command for this slot, if necessary.

slot is the index of the vertex buffer slot that self tracks.

Trait Implementations

impl Debug for VertexState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
