Module queue

This module implements the Queue type, which provides an abstraction over a VmBus channel.

Structs

• BatchRead
  An asynchronous batch read operation.
• CompletionPacket
  A completion packet.
• DataPacket
  An incoming data packet.
• Error
  A queue error.
• OutgoingPacket
  An outgoing packet.
• PacketRef
  A reference to a single packet that has not been read out of the ring yet.
• Queue
  An abstraction over an open VmBus channel that provides methods to read and write packets from the ring, as well as poll the ring for readiness.
• Read
  An asynchronous read operation.
• ReadBatch
  An incoming packet batch reader.
• ReadBatchIter
  The packet iterator for ReadBatch.
• ReadHalf
  The reader for the incoming ring buffer of a Queue.
• Write
  An asynchronous packet write operation.
• WriteBatch
  A batch writer, returned by WriteHalf::batched.
• WriteHalf
  The writer for the outgoing ring buffer of a Queue.

Enums

• ExternalDataError
  An error returned by read_external_ranges
• IncomingPacket
  An incoming packet.
• TryReadError
  An error returned by try_read* methods.
• TryWriteError
  An error returned by try_write* methods.

Functions

• connected_queues
  Returns a pair of connected queues. Useful for testing.
