Function bsn1::try_length_from

pub fn try_length_from(bytes: &[u8]) -> Result<(Length, &[u8]), Error>

Tries to parse bytes starting with 'length' and returns Length .

This function ignores extra octets at the end of bytes .

Warnings

This function may return Ok(Length::Indefinite) , however, 'DER' and 'CER' don't allow such value. It does not always mean bytes is valid that this function returns Ok .

Examples

use bsn1::{length_to_bytes, try_length_from, Length};

let length = Length::Definite(3);
let bytes = length_to_bytes(&length);

let deserialized = try_length_from(bytes.as_ref()).unwrap();
assert_eq!(length, deserialized.0);
