Module io

Available on crate feature std only.

Modules§

ArrayBuf: A fixed-size, inline (stack) owned read buffer, no heap allocation.
BridgeIo: A bidirectional bridge between two Io objects.
CancelIo: Extension type that can be injected into an I/O stream to cancel it gracefully.
ChainReader: Reader that can be used to chain two readers together.
GracefulIo: An I/O wrapper that stops reading and writing once the cancel future resolves.
HeapReader: Reader for reading from a heap-allocated bytes buffer.
PrefixedIo: a stream which has some data prefixed to be read first prior to any other reading.
Slice: A sub-range view [begin, end) of an owned IoBuf, itself an IoBuf.
StackReader: Reader for reading from a stack buffer
Uninit: A read-target view of a buffer’s writable spare [buf_len, capacity): reading into it appends to the underlying (the view’s offset 0 is the underlying’s buf_len). Created by IoBufMut::uninit; recover the buffer with into_inner.

AsyncReadOwned: Read bytes into an owned buffer, returning the buffer with the result.
AsyncWriteOwned: Write bytes from an owned buffer, returning the buffer with the result.
Io: A generic transport of bytes is a type that implements AsyncRead, AsyncWrite and Send. This is specific to Rama and is directly linked to the supertraits of Tokio.
IoBuf: An owned, stable byte buffer that can back an IO read or write.
IoBufMut: An IoBuf that can also be written into (i.e. used as a read destination).
PeekIoProvider: A higher level trait that can be used by services which wish to peek into I/O, often as part of Deep Protocol Inspections (DPI).
SetLen: Declare how many leading bytes of a buffer are initialized.
SplitIo: Split an IO into owned read and write halves usable concurrently.

BufResult: Result of an owned-buffer IO operation: the io::Result plus the buffer handed back to the caller (ownership round-trips through the operation).
