Struct IndexState 

struct IndexState {
    buffer: Arc<Buffer>,
    format: IndexFormat,
    range: Range<BufferAddress>,
    is_dirty: bool,
}

A render bundle’s current index buffer state.

RenderBundleEncoder::finish records the currently set index buffer here, and calls State::flush_index before any indexed draw command to produce a SetIndexBuffer command if one is necessary.

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

Fields

buffer: Arc<Buffer>

format: IndexFormat

range: Range<BufferAddress>

is_dirty: bool

Implementations

fn limit(&self) -> u64

Return the number of entries in the current index buffer.

Panic if no index buffer has been set.

fn flush(&mut self) -> Option<ArcRenderCommand>

Generate a SetIndexBuffer command to prepare for an indexed draw command, if needed.
