Module buffer 

SSBO management: typed buffers, double-buffering, atomic counters, buffer pools, barrier types, memory tracking, mapped ranges, copy engine.

Structs

AtomicCounter

GPU atomic counter buffer. Used for particle birth/death counting, indirect dispatch argument generation, etc.

BufferCopyEngine

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

BufferDebug

Debug utilities for labeling buffers (requires GL_KHR_debug).

BufferHandle

Opaque handle to a GPU buffer (wraps a raw OpenGL buffer name).

BufferPool

A pool that recycles GPU buffers to avoid frequent allocation/deallocation.

BufferRingAllocator

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.

CopyRegion

Describes a region to copy between two buffers.

FieldDescriptor

Metadata about a field within a structured buffer.

IndirectBuffer

Buffer that stores indirect dispatch commands.

IndirectDispatchCommand

Indirect dispatch arguments as laid out in GPU memory.

MappedRange

Represents a mapped sub-range of a buffer for CPU write access. The mapping must be flushed and unmapped before the GPU can read.

MemoryTracker

Tracks total GPU memory allocated through this subsystem.

MultiCounter

Holds multiple atomic counters in a single buffer.

ParticleBuffer

Double-buffered particle storage for ping-pong compute dispatch.

ParticleGpuData

A particle position/velocity datum, tightly packed for GPU.

SharedBufferPool

Thread-safe buffer pool.

StructuredBuffer

A buffer that tracks its internal field layout for shader interop.

TypedBuffer

A strongly-typed GPU Shader Storage Buffer Object.

Enums

BufferBarrierType

Types of memory barriers that can be issued after compute writes.

BufferUsage

Intended usage hint when creating a buffer.

Functions

issue_barrier

Issue a glMemoryBarrier with the given barrier type.

issue_barrier_raw

Issue a glMemoryBarrier with raw bits.

shared_tracker

Create a new shared memory tracker (convenience wrapper).
