Declarative binary reading and writing
This crate provides bit-level, symmetric, serialization/deserialization implementations for structs and enums
Productivity: Deku will generate symmetric reader/writer functions for your type! Avoid the requirement of writing redundant, error-prone parsing and writing code for binary structs or network headers
Compiler support: requires rustc 1.71+

Read big-endian data into a struct, modify a value, and write it
