source§fn fill_buf(&mut self) -> Result<&[u8]>
fn fill_buf(&mut self) -> Result<&[u8]>
Returns the contents of the internal buffer, filling it with more data
from the inner reader if it is empty. Read more
source§fn consume(&mut self, amt: usize)
fn consume(&mut self, amt: usize)
Tells this buffer that
amt
bytes have been consumed from the buffer,
so they should no longer be returned in calls to read
