Crate net_backend

This module defines a trait and implementations thereof for network backends.

Modules

• loopback
  Loopback endpoint implementation, which reflects all transmits back as receives.
• null
  Null (disconnected) endpoint.
• resolve
  Resolver-related definitions for networking backends.
• tests
  Types to help test backends.

Structs

• DisconnectableEndpoint
• DisconnectableEndpointCachedState
• DisconnectableEndpointControl
• MultiQueueSupport
  Multi-queue related support.
• QueueConfig
  Per-queue configuration.
• RssConfig
• RxBufferSegment
  An individual segment in guest memory of a receive buffer.
• RxId
  A receive buffer ID.
• RxMetadata
  Receive packet metadata.
• TxId
  A transmit ID. This may be used by multiple segments at the same time.
• TxMetadata
  Transmit packet metadata.
• TxOffloadSupport
  The set of supported transmit offloads.
• TxSegment
  A transmit packet segment.

Enums

• EndpointAction
• L3Protocol
  The “L3” protocol: the IP layer.
• L4Protocol
  The “L4” protocol: the TCP/UDP layer.
• RxChecksumState
  The receive checksum state for a packet.
• TxSegmentType
  The segment type.

Traits

• BufferAccess
  A trait for providing access to guest memory buffers.
• Endpoint
  A network endpoint.
• Queue
  A trait for sending and receiving network packets.

Functions

• linearize
  Linearizes the next packet in a list of segments, returning the buffer data and advancing the segment list.
• next_packet
  Gets the next packet from a list of segments, returning the packet metadata, the segments in the packet, and the remaining segments.
• packet_count
  Computes the number of packets in segments.
