[RFC] DidUri improvements about did

[dhuseby]

Hrm...if we make the trait called DidUri instead of Did, then we can have a module level method that does the parsing and tries to create instances of the method-specific types that impl the DidUri trait. That way we could just do this:

// this will create an instance of DidGitUri
let git = Did::from_str("did:git:akjsdhgaksdjhgasdkgh").unwrap();

// this will create an instance of DidSovUri
let sov = Did::from_str("did:sov:akjsdhgaksdjhgasdkgh").unwrap();

That's what I'm thinking.

My only concern is that all DIDs have a common format which is the goal of this function. After generic parsing, then you can downcast to the most specific ones, so I’m not sure what the trait buys.

I’m not opposed to having a generic parse that returns the specific instance

I guess that does make more sense. I'm mostly concerned with turning the method specific parts of the DID into instances of objects for that method. for instance, turning the commit hash in a did:git string into a commit object from libgit2.
