Struct vulkano::buffer::cpu_pool::CpuBufferPoolChunk

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.

Trait Implementations

impl<T, A> BufferAccess for CpuBufferPoolChunk<T, A> where
    A: MemoryPool, 

fn inner(&self) -> BufferInner<'_>

Returns the inner information about this buffer.

fn size(&self) -> usize

Returns the size of the buffer in bytes.

fn conflicts_buffer(&self, other: &dyn BufferAccess) -> bool

Returns true if an access to self potentially overlaps the same memory as an access to other.

fn conflicts_image(&self, other: &dyn ImageAccess) -> bool

Returns true if an access to self potentially overlaps the same memory as an access to other.

fn conflict_key(&self) -> (u64, usize)

Returns a key that uniquely identifies the buffer. Two buffers or images that potentially overlap in memory must return the same key.

fn try_gpu_lock(&self, _: bool, _: &Queue) -> Result<(), AccessError>

Locks the resource for usage on the GPU. Returns an error if the lock can't be acquired.

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.

unsafe fn unlock(&self)

Unlocks the resource previously acquired with try_gpu_lock or increase_gpu_lock.

fn as_buffer_slice(&self) -> BufferSlice<Self::Content, &Self> where
    Self: Sized + TypedBufferAccess, 

Builds a BufferSlice object holding the buffer by reference.

fn slice<T>(&self, range: Range<usize>) -> Option<BufferSlice<[T], &Self>> where
    Self: Sized + TypedBufferAccess<Content = [T]>, 

Builds a BufferSlice object holding part of the buffer by reference.

fn into_buffer_slice(self) -> BufferSlice<Self::Content, Self> where
    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]>, 

Builds a BufferSlice object holding part of the buffer by reference.

impl<T, A> Clone for CpuBufferPoolChunk<T, A> where
    A: MemoryPool, 

fn clone(&self) -> CpuBufferPoolChunk<T, A>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T, A> DeviceOwned for CpuBufferPoolChunk<T, A> where
    A: MemoryPool, 

fn device(&self) -> &Arc<Device>

Returns the device that owns Self.

impl<T, A> Drop for CpuBufferPoolChunk<T, A> where
    A: MemoryPool, 

fn drop(&mut self)

Executes the destructor for this type.

impl<T, A> TypedBufferAccess for CpuBufferPoolChunk<T, A> where
    A: MemoryPool, 

type Content = [T]

The type of the content.

fn len(&self) -> usize where
    Self::Content: Content, 

Returns the length of the buffer in number of elements.
