Module rubble::bytes

Utilities for decoding from and encoding into bytes.

This module defines zero-copy (de)serialization traits, ToBytes and FromBytes, as well as the helper structs ByteWriter and ByteReader, which wrap a &mut [u8] or &[u8] and offer useful utilities to read and write values.

All types that end up getting transmitted over the air will want to implement ToBytes and FromBytes. This includes the raw PDUs sent and received on advertising and data channels, as well as messages used by a high-level protocol transferred over L2CAP.

Also defined in this module is the BytesOr type, which can be used to store objects and slices of objects either as a direct reference or as a &[u8] that is lazily decoded.

Structs

ByteReader	Allows reading values from a borrowed byte slice.
ByteWriter	Wrapper around a byte slice that can be used to encode data into bytes.
BytesOr	Reference to a T, or to a byte slice that can be decoded as a T.

Traits

FromBytes	Trait for decoding values from a byte slice.
ToBytes	Trait for encoding a value into a byte buffer.
