Crate netstack3_tcp

Netstack3 core TCP.

This crate contains the TCP implementation for netstack3.

Structs

• BoundInfo
  Information about a bound socket’s address.
• BufferLimits
  Information about the number of bytes in a Buffer.
• BufferSizes
  Named tuple for holding sizes of buffers for a socket.
• ConnectionInfo
  Information about a connected socket’s address.
• DemuxState
  TCP demux state.
• Ipv6Options
  Socket options that are accessible on IPv6 sockets.
• Ipv6SocketIdToIpv4DemuxIdConverter
  A ZST that helps convert IPv6 socket IDs into IPv4 demux IDs.
• IsnGenerator
  A generator of TCP initial sequence numbers.
• NoConnection
  Possible error for calling shutdown on a not-yet connected socket.
• SocketAddr
  Socket address includes the ip address and the port number.
• SocketOptions
  TCP socket options.
• Sockets
  Holds all the TCP socket states.
• TcpApi
  The TCP socket API.
• TcpCountersInner
  The IP agnostic version of TcpCounters.
• TcpSocketId
  A TCP Socket ID.
• TcpSocketSet
  A thin wrapper around a hash map that keeps a set of all the known TCP sockets in the system.
• TcpSocketState
  The state held by a TCP socket.
• TcpState
  Stack wide state supporting TCP.
• UnboundInfo
  Information about an unbound socket.
• WeakTcpSocketId
  A Weak TCP Socket ID.

Enums

• AcceptError
  Possible errors for accept operation.
• BindError
  Possible errors when connecting a socket.
• ConnectError
  Possible errors when connecting a socket.
• ConnectionError
  Errors surfaced to the user.
• ListenError
  Errors for the listen operation.
• OriginalDestinationError
  Possible errors when retrieving the original destination of a socket.
• SetDeviceError
  Error returned when failing to set the bound device for a socket.
• SetReuseAddrError
  Error returned when attempting to set the ReuseAddress option.
• SocketInfo
  Information about a socket.
• TcpIpTransportContext
  An implementation of [IpTransportContext] for TCP.

  Timer ID for TCP connections.

Constants

• DEFAULT_FIN_WAIT2_TIMEOUT
  Default lifetime for a orphaned connection in FIN_WAIT2.

Traits

• Buffer
  Common super trait for both sending and receiving buffer.
• DualStackDemuxIdConverter
  This trait allows us to work around the life-time issue when we need to convert an IPv6 socket ID into an IPv4 demux ID without holding on the a dual-stack CoreContext.
• DualStackIpExt
  A marker trait for dual-stack socket features.
• IntoBuffers
  A conversion trait that converts the object that Bindings give us into a pair of receive and send buffers.
• ListenerNotifier
  A notifier used to tell Bindings about new pending connections for a single socket.
• ReceiveBuffer
  A buffer supporting TCP receiving operations.
• SendBuffer
  A buffer supporting TCP sending operations.
• TcpBindingsContext
  The bindings context for TCP.
• TcpBindingsTypes
  Bindings types for TCP.
• TcpContext
  Core context for TCP.
• TcpDemuxContext
  The core execution context abstracting demux state access for TCP.
• TcpDualStackContext
  A provider of dualstack socket functionality required by TCP sockets.

Type Aliases

• TcpCounters
  TCP Counters.
