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> 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> 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 conflict_key(&self, _: usize, _: usize) -> u64

Returns a key that uniquely identifies the range given by offset/size.

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

Returns the length of the buffer in number of elements.

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.

fn conflicts_buffer(
    &self,
    self_offset: usize,
    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).

fn conflicts_image(
    &self,
    self_offset: usize,
    self_size: usize,
    other: &ImageAccess,
    other_first_layer: u32,
    other_num_layers: u32,
    other_first_mipmap: u32,
    other_num_mipmaps: u32
) -> 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_first_layer, other_num_layers, other_first_mipmap and other_num_mipmaps).

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

Shortcut for conflicts_buffer that compares the whole buffer to another.

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

Shortcut for conflicts_image that compares the whole buffer to a whole image.

fn conflict_key_all(&self) -> u64

Shortcut for conflict_key that grabs the key of the whole buffer.

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

fn drop(&mut self)

A method called when the value goes out of scope.

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

type Content = [T]

The type of the content.

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

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

Returns the device that owns Self.
