Struct DeferredWgpuSlot 

pub struct DeferredWgpuSlot { /* private fields */ }

Available on crate feature wgpu only.

Shared, mutate-once slot the producer fills in after the caller submits the encoded work. Used by SyncPoint::DeferredWgpu.

The slot is initialised to None at mint time and transitions to Some(idx) exactly once via Self::set; subsequent calls are rejected with Error::InvalidArgument (single-shot semantics).

Implementations

impl DeferredWgpuSlot

pub fn new() -> Self

pub fn set(&self, idx: SubmissionIndex) -> Result<(), Error>

Commit the post-submit SubmissionIndex. Single-shot — a second call returns Error::InvalidArgument without overwriting the committed value.

pub fn get(&self) -> Option<&SubmissionIndex>

Return the committed SubmissionIndex, or None if the producer has not yet submitted.
