Struct GpuBufferHandle 

#[repr(transparent)]
pub struct GpuBufferHandle(u32);

GpuBuffer handle is similar to GpuBufferAddress with additional checks to avoid accidentally using the same handle in multiple frames.

Do not send GpuBufferHandle to the GPU directly. Instead use a GpuBuffer or GpuBufferBuilder to resolve the handle into a GpuBufferAddress that can be placed into GPU data.

The extra checks consists into storing an 8 bit epoch in the upper 8 bits of the handle. The epoch will be reused every 255 frames so this is not a mechanism that one can rely on to store and reuse handles over multiple frames. It is only a mechanism to catch mistakes where a handle is accidentally used in the wrong frame and panic.

Implementations

impl GpuBufferHandle

const EPOCH_MASK: u32 = 0xFC000000

fn new(addr: u32, epoch: u32) -> Self

pub fn address_unchecked(&self) -> GpuBufferAddress

Trait Implementations

impl Clone for GpuBufferHandle

fn clone(&self) -> GpuBufferHandle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GpuBufferHandle

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

Formats the value using the given formatter.

impl MallocSizeOf for GpuBufferHandle

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl PartialEq for GpuBufferHandle

fn eq(&self, other: &GpuBufferHandle) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for GpuBufferHandle

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
