Usage

Add hdlc to Cargo.toml

toml [dependencies] hdlc = "^0.2.4"

or

toml [dependencies.hdlc] git = "https://github.com/CLomanno/hdlc"

Add this to crate root

rust extern crate hdlc;

Encode packet

```rust extern crate hdlc; use hdlc::{SpecialChars, encode};

// Set up your vector of bytes and generate your Special Characters let msg: Vec = vec![0x01, 0x50, 0x00, 0x00, 0x00, 0x05, 0x80, 0x09]; let cmp: Vec = vec![0x7E, 0x01, 0x50, 0x00, 0x00, 0x00, 0x05, 0x80, 0x09, 0x7E];

// Encode your message let result = encode(&msg, SpecialChars::default());

assert!(result.isok()); asserteq!(result.unwrap(), cmp); ```

Custom Special Characters

```rust extern crate hdlc; use hdlc::{SpecialChars, encode};

// Set up your vector of bytes and generate your Special Characters let msg: Vec = vec![0x01, 0x7E, 0x70, 0x50, 0x00, 0x05, 0x80, 0x09]; let cmp: Vec = vec![0x71, 0x01, 0x7E, 0x70, 0x50, 0x50, 0x00, 0x05, 0x80, 0x09, 0x71]; let chars = SpecialChars::new(0x71, 0x70, 0x51, 0x50);

// Encode your message let result = encode(&msg, chars);

assert!(result.isok()); asserteq!(result.unwrap(), cmp) ```

Decode packet

```rust extern crate hdlc; use hdlc::{SpecialChars, decode};

// Set up your vector of bytes and generate your Special Characters let msg: Vec = vec![ chars.fend, 0x01, 0x50, 0x00, 0x00, 0x00, 0x05, 0x80, 0x09, chars.fend, ]; let cmp: Vec = vec![0x01, 0x50, 0x00, 0x00, 0x00, 0x05, 0x80, 0x09];

// Decode your message let result = decode(&msg, chars);

assert!(result.isok()); asserteq!(result.unwrap(), cmp); ```

Decode slice packet

```rust extern crate hdlc; use hdlc::{SpecialChars, decode_slice};

// Set up your mutable slice of bytes and generate your Special Characters let chars = SpecialChars::default(); let mut msg = [ chars.fend, 0x01, 0x50, 0x00, 0x00, 0x00, 0x05, 0x80, 0x09, chars.fend, ]; let cmp = [0x01, 0x50, 0x00, 0x00, 0x00, 0x05, 0x80, 0x09];

// Decode your slice let result = decode_slice(&mut msg, chars);

assert!(result.isok()); asserteq!(result.unwrap(), cmp); ```
