pub struct ByteSliceIter<R>where
R: Read,{ /* private fields */ }
Expand description
An iterator over byte slices from a Read
that reuses the same buffer instead of allocating.
See the crate documentation for example usage.
Implementations§
Source§impl<R> ByteSliceIter<R>where
R: Read,
impl<R> ByteSliceIter<R>where
R: Read,
Sourcepub fn new(inner: R, size: usize) -> ByteSliceIter<R>
pub fn new(inner: R, size: usize) -> ByteSliceIter<R>
Create a new ByteSliceIter
that reads from inner
and produces slices of length
chunk_len
. If size
does not divide the total number of bytes read evenly the last
chunk will not have length size
.
