RustCrypto: Object Identifiers (OIDs)
Const-friendly implementation of the ISO/IEC Object Identifier (OID) standard
as defined in ITU X.660, with support for BER/DER encoding/decoding as well
no_std (i.e. embedded) environments.
Object Identifiers, a.k.a. OIDs, are an International Telecommunications Union (ITU) and ISO/IEC standard for naming any object, concept, or "thing" with a globally unambiguous persistent name.
The ITU's X.660 standard provides the OID specification. Every OID is part of a hierarchical namespace which begins with a root OID, which is either the ITU's root OID (0), the ISO's root OID (1), or the joint ISO/ITU root OID (2).
The following is an example of an OID, in this case identifying the
For more information, see: https://en.wikipedia.org/wiki/Object_identifier
This library supports parsing OIDs in const contexts, e.g.:
use const_oid::ObjectIdentifier; pub const MY_OID: ObjectIdentifier = ObjectIdentifier::new("1.2.840.113518.104.22.168");
The OID parser is implemented entirely in terms of
const fn and without the
use of proc macros.
Additionally, it also includes a
const fn OID serializer, and stores the OIDs
parsed from const contexts encoded using the BER/DER serialization

AsRef<[u8]> which can be used to
obtain the BER/DER serialization of an OID, even one declared
Additionally, it impls
TryFrom<&[u8]> and functions just as
well as a runtime OID library.
