Struct BufferCopyEngine 

pub struct BufferCopyEngine { /* private fields */ }

Performs GPU-side buffer-to-buffer copies without CPU readback.

Implementations

impl BufferCopyEngine

pub fn new() -> Self

Create a new copy engine.

pub fn copy( &mut self, gl: &Context, src: BufferHandle, src_offset: usize, dst: BufferHandle, dst_offset: usize, length: usize, )

Copy length bytes from src at src_offset to dst at dst_offset. All offsets and lengths are in bytes.

pub fn copy_full(&mut self, gl: &Context, src: BufferHandle, dst: BufferHandle)

Copy the entire source buffer into destination at offset 0.

pub fn copy_regions( &mut self, gl: &Context, src: BufferHandle, dst: BufferHandle, regions: &[CopyRegion], )

Scatter-copy: copy multiple disjoint regions in a single call.

pub fn total_bytes_copied(&self) -> u64

Total bytes copied across all operations.

pub fn copy_count(&self) -> u64

Total number of copy operations.

pub fn reset_stats(&mut self)

Reset statistics.

impl Default for BufferCopyEngine

fn default() -> Self

Returns the “default value” for a type.
