This is a Rust crate for working with DID documents as defined in the Decentralized Identifier Spec.
This crate currently supports two functions: parsing and verifying DID URIs and DID Documents. It does not handle DID method specs which are more specific to a network or context.
The namespace is did_uri with top level re-exports of Uri, Document,
DidError, DidErrorKind.
Example of parsing a DID Uri:
use did_doc::Uri;
fn main() {
//Valid DID URI
let did = Uri::from_str("did:git:akjsdhgaksdjhgasdkgh").unwrap();
//Invalid DID URI
let res = Uri::from_str("did:git:");
assert!(res.is_err());
//Convert back to string
let did_str = did.to_string();
}Example of parsing a DID Document:
use did_doc::{
fields::{PublicKeyEncoding, PublicKeyType},
Document
};
fn main() {
let jstr = r#"
{
"@context": "https://w3id.org/did/v1",
"id": "did:example:123456789abcdefghi"
}
"#;
//Valid did document;
let doc = Document::from_str(&jstr).unwrap();
assert_eq!(doc.context().len(), 1);
assert_eq!(doc.subject(), "did:example:123456789abcdefghi");
assert_eq!(doc.public_key().len(), 0);
assert_eq!(doc.authentication().len(), 0);
assert_eq!(doc.service().len(), 0);
