Struct gzip_header::CrcReader
[−]
[src]
pub struct CrcReader<R> { /* fields omitted */ }
A reader that updates the checksum and counter of a Crc
struct when reading from the wrapped
reader.
Methods
impl<R: Read> CrcReader<R>
[src]
fn new(r: R) -> CrcReader<R>
Create a new CrcReader
with a blank checksum.
fn crc(&self) -> &Crc
Return a reference to the underlying checksum struct.
fn into_inner(self) -> R
Consume this CrcReader
and return the wrapped Read
instance.
fn inner(&mut self) -> &mut R
Return a mutable reference to the wrapped reader.
fn reset(&mut self)
Reset the checksum and counter.

fn fill_buf(&mut self) -> Result<&[u8]>
Fills the internal buffer of this object, returning the buffer contents. Read more
fn consume(&mut self, amt: usize)
Tells this buffer that amt
