pub struct CpuBufferPoolSubbuffer<T, A> where
[T]: BufferContents,
A: MemoryPool, { /* private fields */ }Expand description
A subbuffer allocated from a CpuBufferPool.
When this object is destroyed, the subbuffer is automatically reclaimed by the pool.

sourcefn inner(&self) -> BufferInner<'_>
fn inner(&self) -> BufferInner<'_>
Returns the inner information about this buffer.
sourcefn size(&self) -> DeviceSize
fn size(&self) -> DeviceSize
Returns the size of the buffer in bytes.
sourcefn conflict_key(&self) -> (u64, u64)
fn conflict_key(&self) -> (u64, u64)
Returns a key that uniquely identifies the buffer. Two buffers or images that potentially overlap in memory must return the same key. Read more
sourcefn try_gpu_lock(&self, e: bool, q: &Queue) -> Result<(), AccessError>
fn try_gpu_lock(&self, e: bool, q: &Queue) -> Result<(), AccessError>
Locks the resource for usage on the GPU. Returns an error if the lock can’t be acquired. Read more
sourceunsafe fn increase_gpu_lock(&self)
unsafe fn increase_gpu_lock(&self)
Locks the resource for usage on the GPU. Supposes that the resource is already locked, and simply increases the lock by one. Read more
