only.Expand description
BufReader
used by Decoder
when it is constructed with Decoder::new_bufferless
Implementations
Creates a new BufReader
with a default buffer capacity. The default is currently 8 KB,
but may change in the future.
Creates a new BufReader
with the specified buffer capacity.
Gets a reference to the underlying reader.
It is inadvisable to directly read from the underlying reader.
Gets a mutable reference to the underlying reader.
It is inadvisable to directly read from the underlying reader.
Gets a pinned mutable reference to the underlying reader.
It is inadvisable to directly read from the underlying reader.
Consumes this BufWriter
, returning the underlying reader.
Note that any leftover data in the internal buffer is lost.

Tells this buffer that amt
bytes have been consumed from the buffer,
so they should no longer be returned in calls to read
. Read more

byte) is reached, and append
them to the provided buffer. Read more

byte
. Read more
