pub struct HybridRleDecoder<'a> { /* private fields */ }Expand description
A Iterator for Hybrid Run-Length Encoding
The hybrid here means that each second is prepended by a bit that differentiates between two modes.
- Run-Length Encoding in the shape of
[Number of Values, Value] - Bitpacking in the shape of
[Value 1 in n bits, Value 2 in n bits, ...]
Note, that this can iterate, but the set of collect_* and translate_and_collect_* methods
should be highly preferred as they are way more efficient and have better error handling.
