Struct vulkano::buffer::cpu_pool::CpuBufferPoolChunk
[−]
[src]
pub struct CpuBufferPoolChunk<T, A> where
A: MemoryPool, { /* fields omitted */ }
A subbuffer allocated from a CpuBufferPool
.
When this object is destroyed, the subbuffer is automatically reclaimed by the pool.

fn inner(&self) -> BufferInner
[src]
Returns the inner information about this buffer.
fn size(&self) -> usize
[src]
Returns the size of the buffer in bytes.
fn conflict_key(&self, _: usize, _: usize) -> u64
[src]
Returns a key that uniquely identifies the range given by offset/size. Read more
fn try_gpu_lock(&self, _: bool, _: &Queue) -> Result<(), AccessError>
[src]
Locks the resource for usage on the GPU. Returns an error if the lock can't be acquired. Read more
unsafe fn increase_gpu_lock(&self)
[src]
Locks the resource for usage on the GPU. Supposes that the resource is already locked, and simply increases the lock by one. Read more
unsafe fn unlock(&self)
[src]
Unlocks the resource previously acquired with try_gpu_lock
or increase_gpu_lock
. Read more

Self: Sized + TypedBufferAccess<Content = [T]>,
[src]
Self: Sized + TypedBufferAccess<Content = [T]>,
Builds a BufferSlice
object holding part of the buffer by reference. Read more
fn into_buffer_slice(self) -> BufferSlice<Self::Content, Self> where
Self: Sized + TypedBufferAccess,
[src]
Self: Sized + TypedBufferAccess,
Builds a BufferSlice
object holding the buffer by value.
fn index<T>(&self, index: usize) -> Option<BufferSlice<[T], &Self>> where
Self: Sized + TypedBufferAccess<Content = [T]>,
[src]
Self: Sized + TypedBufferAccess<Content = [T]>,
Builds a BufferSlice
object holding part of the buffer by reference. Read more

self_size: usize,
other: &BufferAccess,
_other_offset: usize,
_other_size: usize
) -> bool
Returns true if an access to self
(as defined by self_offset
and self_size
) potentially overlaps the same memory as an access to other
(as defined by other_offset
and other_size
). Read more
