Function yasna::construct_der

pub fn construct_der<F>(callback: F) -> Vec<u8> where
    F: FnOnce(DERWriter<'_>), 

Constructs DER-encoded data as Vec<u8>.

This function uses the loan pattern: callback is called back with a DERWriter, to which the ASN.1 value is written.

Examples

use yasna;
let der = yasna::construct_der(|writer| {
    writer.write_sequence(|writer| {
        writer.next().write_i64(10);
        writer.next().write_bool(true);
    })
});
assert_eq!(der, vec![48, 6, 2, 1, 10, 1, 1, 255]);
