Deku

Declarative binary reading and writing

This crate provides bit-level, symmetric, serialization/deserializationimplementations for structs and enums

Why use Deku

Productivity: Deku will generate symmetric reader/writer functions for your type!Avoid the requirement of writing redundant, error-prone parsing and writing codefor binary structs or network headers

Usage

Compiler support: requires rustc 1.71+

[dependencies]deku ="0.18"

no_std:

[dependencies]deku = {version ="0.18",default-features =false,features = ["alloc"] }

Example

Seedocumentation orexamples folder for more!

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

use deku::prelude::*;#[derive(Debug,PartialEq,DekuRead,DekuWrite)]#[deku(endian ="big")]structDekuTest{#[deku(bits =4)]field_a:u8,#[deku(bits =4)]field_b:u8,field_c:u16,}fnmain(){let data:Vec<u8> =vec![0b0110_1001,0xBE,0xEF];let(_rest,mut val) =DekuTest::from_bytes((data.as_ref(),0)).unwrap();assert_eq!(DekuTest{        field_a:0b0110,        field_b:0b1001,        field_c:0xBEEF,}, val);    val.field_c =0xC0FE;let data_out = val.to_bytes().unwrap();assert_eq!(vec![0b0110_1001,0xC0,0xFE], data_out);}
