Struct StreamAllocation 

pub struct StreamAllocation { /* private fields */ }

Handle to a stream-ordered memory allocation.

An allocation lives on the GPU and is associated with a specific stream and memory pool. It becomes available when all preceding work on the stream has completed, and is returned to the pool when freed (also stream-ordered).

Implementations

impl StreamAllocation

pub fn as_ptr(&self) -> u64

Returns the device pointer as a raw u64 (CUdeviceptr).

pub fn size(&self) -> usize

Returns the allocation size in bytes.

pub fn is_freed(&self) -> bool

Returns true if this allocation has been freed.

pub fn stream(&self) -> u64

Returns the stream handle this allocation is ordered on.

pub fn stream_id(&self) -> StreamOrderId

Returns the ordering identifier of the stream this allocation is bound to in the owning pool’s stream-ordered model.

pub fn ready_seq(&self) -> u64

Returns the sequence number at which this allocation becomes valid on its stream within the owning pool’s StreamOrderModel.

The allocation is safe to read on its own stream only once that stream has executed past this point (queryable via StreamMemoryPool::is_ready).

pub fn pool(&self) -> u64

Returns the pool handle that owns this allocation.
