Struct termion::AsyncReader

pub struct AsyncReader { /* fields omitted */ }

An asynchronous reader.

This acts as any other stream, with the exception that reading from it won't block. Instead, the buffer will only be partially updated based on how much the internal buffer holds.

Trait Implementations

impl Read for AsyncReader

fn read(&mut self, buf: &mut [u8]) -> Result<usize>

Read from the byte stream.

This will never block, but try to drain the event queue until empty. If the total number of bytes written is lower than the buffer's length, the event queue is empty or that the event stream halted.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>

Read all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Read all bytes until EOF in this source, placing them into buf.

fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), Error>

Read the exact number of bytes required to fill buf.

fn by_ref(&mut self) -> &mut Self

Creates a "by reference" adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

Transforms this Read instance to an Iterator over its bytes.

fn chars(self) -> Chars<Self>

Unstable (io)

: the semantics of a partial read/write of where errors happen is currently unclear and may change

Transforms this Read instance to an Iterator over chars.

fn chain<R>(self, next: R) -> Chain<Self, R> where R: Read

Creates an adaptor which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

Creates an adaptor which will read at most limit bytes from it.
