WebGpuFrameArena class final

A bump allocator over one GPUBuffer, reset every frame. See the library comment, which is where the argument for this shape is.

Constructors

WebGpuFrameArena(GPUDevice _gpu, {required int usage, required int alignment, required String label, int initialBytes = 1 << 16})

alignment → int: What every allocation's offset is rounded up to.
final
bufferCount → int: How many GPUBuffers this arena is holding, for WebGpuDevice.debugTrackedResourceCount. One, until a frame overflows it, and zero once dispose has destroyed them.
no setter
hashCode → int: The hash code for this object.
no setterinherited
label → String: What the browser calls this buffer when it complains about it.
final
peakBytes → int: The high-water mark since the arena was made, in bytes: what the largest frame so far asked of it. Diagnostic — read by dispose_test.dart, which asserts that a frame's second run allocates nothing new.
no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
usage → int: What the buffer may be bound as — uniform, vertex or index — beside COPY_DST, which every arena needs and this adds.
final

dispose() → void: Destroys every buffer this arena holds. Called from dispose, once.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
reset() → void: Back to the start, at the top of a frame. Safe under a frame the GPU has not finished — the library comment is the argument.
toString() → String: A string representation of this object.
inherited
write(ByteData bytes) → WebGpuSlice: bytes written into the arena, and where they went.
