• MetricsInfo
• Queue
  Shared Queues in proxy-wasm are a FIFO MPMC queue with no message duplication. Any WASM VM can resolve a queue or register new ones in their own VM ID. Any WASM VM can dequeue data, which will globally dequeue that item. Messages are not replicated to each WASM VM. When broadcasting data to many WASM VMs, it’s advised to have a scheme where each thread can register it’s own inbound queue, then enqueue the name of said queue to the centralized source of data. That source then enqueues to each WASM VM’s queue individually.
• RequestBody
• RequestHeaders
  Request header context
• RequestTrailers
• ResponseBody
• ResponseHeaders
• ResponseTrailers
• SharedData
  A VM ID local atomic field. Any WASM VM in the same VM ID can read or write to any key in it’s VM ID. SharedData cannot cross VM IDs.
• StreamClose
  Context for a stream closing event
• Upstream
  A reference to an upstream cluster. In envoy this is an encoded protobuf. See Upstream::envoy_upstream.
• UpstreamData
  Upstream data reference for a Stream filter
