class `TGpuBufferSuballocation`

template<bool IsRenderProxy>

Represents a single sub-allocation within a specific GpuBuffer.

Templated to support both main thread and render thread variants.

Public

TGpuBufferSuballocation<IsRenderProxy>() = default

explicit TGpuBufferSuballocation<IsRenderProxy>(const SPtr<GpuBufferType> &buffer, u32 suballocationOffset = 0)

const SPtr<GpuBufferType> &GetBuffer() const

Gets the underlying GPU buffer.

u32 GetSuballocationIndex() const

Gets the zero-based suballocation index within the buffer.

Computed lazily from offset.

u32 GetSuballocationOffset() const

Gets the byte offset from the start of the buffer for this suballocation.

u32 GetSize() const

Gets the size of this suballocation in bytes (aligned).

May be larger than requested size during buffer creation due to alignment requirements.

bool IsValid() const

Checks if this is a valid suballocation.

void Reset()

Clears the suballocation, making it invalid.

TGpuBufferMappedScope<IsRenderProxy> Map(GpuMapOptions options = GpuMapOption::Write) const

Maps this suballocation for CPU access.

Returns: RAII mapped region that auto-flushes on destruction.
