sourceimpl<R: Read> Input for IoReader<R>
impl<R: Read> Input for IoReader<R>
sourcefn remaining_len(&mut self) -> Result<Option<usize>, Error>
fn remaining_len(&mut self) -> Result<Option<usize>, Error>
Should return the remaining length of the input data. If no information about the input
length is available, None should be returned. Read more
sourcefn read(&mut self, into: &mut [u8]) -> Result<(), Error>
fn read(&mut self, into: &mut [u8]) -> Result<(), Error>
Read the exact number of bytes required to fill the given buffer. Read more
sourcefn descend_ref(&mut self) -> Result<(), Error>
fn descend_ref(&mut self) -> Result<(), Error>
Descend into nested reference when decoding.
This is called when decoding a new refence-based instance,
such as Vec or Box. Currently all such types are
allocated on the heap. Read more
sourcefn ascend_ref(&mut self)
fn ascend_ref(&mut self)
Ascend to previous structure level when decoding. This is called when decoding reference-based type is finished. Read more
