Module url 

DID URL parsing and dereferencing.

A DID URL is a DID plus optional path, query, and/or fragment components, per W3C DID Core §3.2:

did-url     = did path-abempty [ "?" query ] [ "#" fragment ]
path-abempty = *( "/" segment )

Examples:

• did:ndn:BwkI...#key-0 — fragment reference to a verification method
• did:ndn:BwMg...#key-agreement-1 — zone DID key agreement VM
• did:ndn:BwkI.../service?type=ndn#endpoint — service lookup

(The method-specific identifier is base64url — no colons.)

Dereferencing

deref_did_url takes a parsed DID URL and a resolved DidDocument and returns the specific resource the URL identifies — a verification method, a service, or the full document (when no fragment).

Structs
