io
only.Creates a future which will wait for a non-empty buffer to be available from this I/O object or EOF to be reached. Read more
io
only.A convenience for calling AsyncBufRead::consume
on Unpin
IO types. Read more
io
only.Creates a future which will read all the bytes associated with this I/O
object into buf
until the delimiter byte
or EOF is reached.
This method is the async equivalent to BufRead::read_until
. Read more
io
only.Creates a future which will read all the bytes associated with this I/O
object into buf
until a newline (the 0xA byte) or EOF is reached,
This method is the async equivalent to BufRead::read_line
. Read more
io
only.Creates an adaptor which will chain this stream with another. Read more
io
only.Tries to read some bytes directly into the given buf
in asynchronous
manner, returning a future type. Read more
