nom-teltonika, easily parse the teltonika protocol

This package makes use of the nom crate to parse the binary packets.

Further documentation about the nom crate can be found at the docs.rs page and at the official github page.

Features

It parses Codec 8, 8-Extended and 16 (aka TCP/UDP Protocol).

It DOES NOT parse Codec 12, 13 and 14 (aka GPRS Protocol), it MAY in the future.

It fails parsing if any of the following checks fail:

• Preamble MUST BE 0x00000000
• CRCs DOES NOT match
• Record Counts DOES NOT match
• UDP Un-usable byte MUST BE 0x01

Example

Imei parsing

```rust let imei_buffer = [0x00, 0x0F, 0x33, 0x35, 0x36, 0x33, 0x30, 0x37, 0x30, 0x34, 0x32, 0x34, 0x34, 0x31, 0x30, 0x31, 0x33 ];

let (rest, imei) = nomteltonika::parser::imei(&imeibuffer).unwrap();

asserteq!(rest, &[]); asserteq!(imei, String::from("356307042441013")); ```

Tcp Packet parsing

```rust let buffer = [0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x36, 0x08, 0x01, 0x00, 0x00, 0x01, 0x6B, 0x40, 0xD8, 0xEA, 0x30, 0x01, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x01, 0x05, 0x02, 0x15, 0x03, 0x01, 0x01, 0x01, 0x42, 0x5E, 0x0F, 0x01, 0xF1, 0x00, 0x00, 0x60, 0x1A, 0x01, 0x4E, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x01, 0x00, 0x00, 0xC7, 0xCF ];

let (rest, packet) = nomteltonika::parser::tcppacket(&buffer).unwrap();

assert_eq!(rest, &[]); println!("{packet:#?}"); ```
