Expand description

Helper object for creating FromBer/FromDer types for TAGGED OPTIONAL types

When parsing ContextSpecific (the most common class), see TaggedExplicit and TaggedImplicit alias types.

§Notes

CLASS must be between 0 and 4. See Class for possible values for the CLASS parameter.

§Examples

To parse a [APPLICATION 0] EXPLICIT INTEGER object:

use asn1_rs::{Explicit, FromBer, Integer, TaggedValue};

let bytes = &[0x60, 0x03, 0x2, 0x1, 0x2];

// If tagged object is present (and has expected tag), parsing succeeds:
let (_, tagged) = TaggedValue::<Integer, Explicit, 0b01, 0>::from_ber(bytes).unwrap();
assert_eq!(tagged, TaggedValue::explicit(Integer::from(2)));

source§

fn quirk(&self, value: Quirk) -> Painted<&T>
