# Bit-Slice De/Serialization Bit-slice references and containers serialize as sequences with additional metadata. Serde only provides a deserializer for `&[u8]`; wider integers and interior-mutability wrappers are not able to view a transport buffer without potentially modifying it, and the buffer is not modifiable while being used for deserialization. As such, only `&BitSlice` has a no-copy deserialization implementation. If you need other storage types, you will need to deserialize into a `BitBox` or `BitVec`. If you do not have an allocator, you must *serialize from* and deserialize into a `BitArray`.
