torch.DeviceBuffer

export interface DeviceBuffer {
  /** Unique buffer identifier */
  readonly id: string;

  /** Buffer size in bytes */
  readonly size: number;

  /** Buffer usage flags */
  readonly usage: readonly BufferUsage[];

  /** Release buffer resources */
  destroy(): void;

  /**
   * Map buffer for CPU access (optional).
   * Not all device types support mapping.
   */
  mapAsync?(mode: 'read' | 'write'): Promise<ArrayBuffer>;

  /** Unmap buffer after CPU access */
  unmap?(): void;
}

readonlyid(string): – Unique buffer identifier
readonlysize(number): – Buffer size in bytes
readonlyusage(readonly BufferUsage[]): – Buffer usage flags
destroy(() => void): – Release buffer resources
mapAsync((mode: 'read' | 'write') => Promise<ArrayBuffer>)optional: – Map buffer for CPU access (optional). Not all device types support mapping.
unmap(() => void)optional: – Unmap buffer after CPU access

Abstract device buffer interface.

Device backends implement this interface to provide buffer management.
