DID

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.

For handling DID URIs use the DidUri class found in did::uri::DidUri::from_str.

Example ```rust use did::uri::DidUri;

fn main() { //Valid DID URI let did = DidUri::from_str("did:git:akjsdhgaksdjhgasdkgh").unwrap();

//Invalid DID URI
let res = DidUri::from_str("did:git:");
assert!(res.is_err());

//Convert back to string
let did_str = did.to_string();

} ```

For handling DID Document parsing use did::Document.

Example ```rust use did::{ 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);

} ```
