Module tokio_core::io [] [src]

I/O conveniences when working with primitives in tokio-core

Contains various combinators to work with I/O objects and type definitions as well.

Structs

Copy

A future which will copy all data from a reader into a writer.

EasyBuf

A reference counted buffer of bytes.

EasyBufMut

An RAII object returned from get_mut which provides mutable access to the underlying Vec<u8>.

Flush

A future used to fully flush an I/O object.

Framed

A unified Stream and Sink interface to an underlying Io object, using the Encode and Decode traits to encode and decode frames.

Read

A future which can be used to easily read available number of bytes to fill a buffer.

ReadExact

A future which can be used to easily read exactly enough bytes to fill a buffer.

ReadHalf

The readable half of an object returned from Io::split.

ReadToEnd

A future which can be used to easily read the entire contents of a stream into a vector.

ReadUntil

A future which can be used to easily read the contents of a stream into a vector until the delimiter is reached.

Window

A owned window around an underlying buffer.

WriteAll

A future used to write the entire contents of some data to a stream.

WriteHalf

The writable half of an object returned from Io::split.

Traits

Codec

Encoding and decoding of frames via buffers.

Io

A trait for read/write I/O objects

Functions

copy

Creates a future which represents copying all the bytes from one object to another.

flush

Creates a future which will entirely flush an I/O object and then yield the object itself.

read

Tries to read some bytes directly into the given buf in asynchronous manner, returning a future type.

read_exact

Creates a future which will read exactly enough bytes to fill buf, returning an error if EOF is hit sooner.

read_to_end

Creates a future which will read all the bytes associated with the I/O object A into the buffer provided.

read_until

Creates a future which will read all the bytes associated with the I/O object A into the buffer provided until the delimiter byte is reached. This method is the async equivalent to BufRead::read_until.

write_all

Creates a future that will write the entire contents of the buffer buf to the stream a provided.

Type Definitions

IoFuture

A convenience typedef around a Future whose error component is io::Error

IoStream

A convenience typedef around a Stream whose error component is io::Error
