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]);
