Extracting a range of bits from binary data
To help developing applications, which extract bit level data from a binary source such as spacecraft telemetry
Experimental
This crate is published at crates.io. The detailed documentation is available at docs.rs/bitlab
0.2.1
Just add the following line under [dependencies] to your Cargo.toml file
bitlab = "0.2.1"
Start at bit offset 1, extract 3 bits and interpret the result as u8
rust
use bitlab::*;
let a: i8 = -33; // = 0b1101_1111;
let b = a.get_u8(1, 3).unwrap(); // 1 --> 101 <-- 1111
// = 5
//assert_eq!(b, 5);
The data source is a vector of u8 types. We want to go to byte offset 1, bit offset 7 and starting from there extract 3 bits as an u16
rust
use bitlab::*;
let v: Vec<u8> = vec!{ 0x48, 0x61, 0x6C, 0x6C, 0x6F }; // = "Hallo"
let bar = v.get_u16(1, 7, 3); // relevant bytes = 0x616C = 0b0110_000 --> 1_01 <-- 10_1100
// = 5
assert_eq!(bar.unwrap(), 5);
