Struct BufferRingAllocator 

pub struct BufferRingAllocator { /* private fields */ }

A ring allocator for streaming per-frame data into a large buffer. Each frame gets a slice of the ring; after N frames the oldest slice is reused.

Implementations

impl BufferRingAllocator

pub fn create( gl: &Context, frame_count: usize, frame_size: usize, tracker: Arc<MemoryTracker>, ) -> Self

Create a ring allocator with frame_count slots, each of frame_size bytes.

pub fn advance(&mut self) -> usize

Advance to the next frame slot. Returns the byte offset for this frame’s data.

pub fn write_current(&self, gl: &Context, data: &[u8])

Write data to the current frame slot.

pub fn current_frame(&self) -> usize

Current frame index.

pub fn frame_offset(&self, frame: usize) -> usize

Byte offset for a given frame index.

pub fn handle(&self) -> BufferHandle

Handle to the underlying buffer.

pub fn frame_size(&self) -> usize

Per-frame size in bytes.

pub fn total_size(&self) -> usize

Total size in bytes.

pub fn destroy(self, gl: &Context)

Destroy the ring buffer.
