Struct wgpu_core::resource::StagingBuffer
source · pub struct StagingBuffer<A: Api> { /* private fields */ }Expand description
A temporary buffer, consumed by the command that uses it.
A StagingBuffer is designed for one-shot uploads of data to the GPU. It
is always created mapped, and the command that uses it destroys the buffer
when it is done.
StagingBuffers can be created with queue_create_staging_buffer and
used with queue_write_staging_buffer. They are also used internally by
operations like queue_write_texture that need to upload data to the GPU,
but that don’t belong to any particular wgpu command buffer.
Used StagingBuffers are accumulated in Device::pending_writes, to be
freed once their associated operation’s queue submission has finished
execution.
