Struct asn1_rs::TaggedValue
source · pub struct TaggedValue<T, E, TagKind, const CLASS: u8, const TAG: u32> { /* private fields */ }
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.
Constants from this class can be used, but they must be wrapped in braces due to
Rust syntax for generics
(see example below).
Examples
To parse a [APPLICATION 0] EXPLICIT INTEGER
object:
use asn1_rs::{Class, Error, 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, Error, Explicit, {Class::APPLICATION}, 0>::from_ber(bytes)
.unwrap();
assert_eq!(tagged, TaggedValue::explicit(Integer::from(2)));
