Struct Buffer

pub struct Buffer {
    storage: Arc<UnsafeCell<[u8]>>,
    size: usize,
}

Fields

storage: Arc<UnsafeCell<[u8]>>

This data is potentially accessed mutably in arbitrary non-overlapping slices, so we must store it in UnsafeCell to avoid making any too-strong no-aliasing claims.

size: usize

Size of the allocation.

This is redundant with storage.get().len(), but that method is not available until our MSRV is 1.79 or greater.

Implementations

impl Buffer

pub(super) fn new(desc: &BufferDescriptor<'_>) -> Result<Self, DeviceError>

pub(super) fn get_slice_ptr(&self, range: MemoryRange) -> *mut [u8]

Returns a pointer to the memory owned by this buffer within the given range.

This may be used to create any number of simultaneous pointers; aliasing is only a concern when actually reading, writing, or converting the pointer to a reference.

Trait Implementations

impl Clone for Buffer

fn clone(&self) -> Buffer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Buffer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl DynResource for Buffer

fn as_any(&self) -> &dyn Any

fn as_any_mut(&mut self) -> &mut dyn Any

impl DynBuffer for Buffer

impl Send for Buffer

SAFETY: This shared mutable data will not be accessed in a way which causes data races; the obligation to do so is on the caller of the HAL API. For safe code, wgpu-core validation manages appropriate access.
