Network I/O utilities.

Modules

async_ready 🔒

dns 🔒

framed 🔒

read_exact 🔒

socket 🔒

timeout 🔒

Async{Read,Write} wrappers that enforce a configurable timeout on each I/O operation.

Structs

FrameTooBig

An error indicating that a frame in a framed stream exceeded MAX_FRAME_SIZE.

ReadExactOrEof

A future which reads exactly enough bytes to fill a buffer, unless EOF is reached first.

TimedReader

An AsyncRead wrapper that enforces a timeout on each read.

TimedWriter

An AsyncWrite wrapper that enforces a timeout on each write.

UnixSocketAddr

An address associated with a Unix domain socket.

Enums

DnsResolutionError

An error returned by resolve_address.

Listener

A listener bound to either a TCP socket or Unix domain socket.

SocketAddr

An address associated with an internet or Unix domain socket.

SocketAddrType

The type of a SocketAddr.

Stream

A stream associated with either a TCP socket or a Unix domain socket.

Constants

DUMMY_DNS_PORT

We must provide a port for dns resolution but dns resolution ignores the port so we use a port that is easy to spot in logs.

MAX_FRAME_SIZE

The maximum allowable size of a frame in a framed stream.

Traits

AsyncReady

Asynchronous IO readiness.

Functions

read_exact_or_eof

Creates a future which will read exactly enough bytes to fill buf, unless EOF is reached first. If a short read should be considered an error, use tokio::io::AsyncReadExt::read_exact instead.

resolve_address

Resolves a host address and ensures it is a global address when enforce_global is set. This parameter is useful when connecting to user-defined unverified addresses.
