Struct read_byte_slice::ByteSliceIter
[−]
[src]
pub struct ByteSliceIter<R> where
R: Read, { /* fields omitted */ }
An iterator over byte slices from a Read
that reuses the same buffer instead of allocating.
See the crate documentation for example usage.
Methods
impl<R> ByteSliceIter<R> where
R: Read,
[src]
R: Read,
fn new(inner: R, size: usize) -> ByteSliceIter<R>
[src]
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
.
