Struct RingBuffer 

pub struct RingBuffer { /* private fields */ }

A ring buffer for streaming per-frame data.

Ring buffers cycle through multiple frames worth of buffer space to avoid stalling the GPU pipeline.

Implementations

impl RingBuffer

pub fn new( context: Arc<GraphicsContext>, size: u64, usage: BufferUsages, ) -> Self

Create a new ring buffer.

Arguments

• context - Graphics context
• size - Total size in bytes (will be multiplied by RING_BUFFER_FRAMES)
• usage - Buffer usage flags (UNIFORM, STORAGE, etc.)

pub fn allocate( &mut self, size: u64, alignment: u64, ) -> Option<RingBufferAllocation>

Allocate a region from the ring buffer.

Arguments

• size - Size in bytes to allocate
• alignment - Required alignment (typically 256 for uniforms)

Returns

Returns Some(allocation) if space is available, None if the buffer is full.

pub fn next_frame(&mut self)

Advance to the next frame.

Call this at the beginning or end of each frame to reset the ring buffer for the next frame’s allocations.

pub fn reset(&mut self)

Reset the ring buffer (useful for testing or manual control).

pub fn frame(&self) -> u64

Get the current frame number.

pub fn offset(&self) -> u64

Get the current offset.

pub fn size(&self) -> u64

Get the total size.

pub fn remaining(&self) -> u64

Get remaining space in current frame.
