pub struct SliceReader<'a> { /* private fields */ }
Expand description
Implements ByteReader trait for a slice of bytes.
NOTE: If you are building with the std
feature, you should probably prefer std::io::Cursor
instead. However, SliceReader is still useful in no-std environments until stabilization of
the core_io_borrowed_buf
feature.
