Struct BufferSlice

pub struct BufferSlice<'a> { /* private fields */ }

Implementations

impl<'a> BufferSlice<'a>

pub fn id(&self) -> BufferId

pub fn offset(&self) -> BufferAddress

pub fn size(&self) -> BufferAddress

Methods from Deref<Target = BufferSlice<'a>>

pub fn map_async( &self, mode: MapMode, callback: impl FnOnce(Result<(), BufferAsyncError>) + WasmNotSend + 'static, )

Map the buffer. Buffer is ready to map once the callback is called.

For the callback to complete, either queue.submit(..), instance.poll_all(..), or device.poll(..) must be called elsewhere in the runtime, possibly integrated into an event loop or run on a separate thread.

The callback will be called on the thread that first calls the above functions after the gpu work has completed. There are no restrictions on the code you can run in the callback, however on native the call to the function will not complete until the callback returns, so prefer keeping callbacks short and used to set flags, send messages, etc.

pub fn get_mapped_range(&self) -> BufferView<'a>

Gain read-only access to the bytes of a mapped Buffer.

Return a BufferView referring to the buffer range represented by self. See the documentation for BufferView for details.

Panics

• This panics if the buffer to which self refers is not currently mapped.

• If you try to create overlapping views of a buffer, mutable or otherwise, get_mapped_range will panic.

pub fn get_mapped_range_mut(&self) -> BufferViewMut<'a>

Gain write access to the bytes of a mapped Buffer.

Return a BufferViewMut referring to the buffer range represented by self. See the documentation for BufferViewMut for more details.

Panics

• This panics if the buffer to which self refers is not currently mapped.

• If you try to create overlapping views of a buffer, mutable or otherwise, get_mapped_range_mut will panic.
