Expand description

A library to parse and emit BER-TLV data.

#Examples

Parse TLV:

use tlv_parser::tlv::{Tlv, Value};

let input: Vec<u8> = vec![0x21, 0x05, 0x22, 0x03, 0x03, 0x01, 0xaa];
let tlv = Tlv::from_vec( &input ).unwrap();

if let Some(&Value::Val(ref val)) = tlv.find_val("21 / 22 / 03") {
    assert_eq!(*val, vec![0xaa]);
}

Emit constructed TLV incapsulated primitive TLV:

use tlv_parser::tlv::*;

let primitive_tlv = Tlv::new(0x01, Value::Nothing).unwrap();
let constructed_tlv = Tlv::new(0x21, Value::TlvList(vec![primitive_tlv])).unwrap();

assert_eq!(constructed_tlv.to_vec(), vec![0x21, 0x02, 0x01, 0x00]);
