Enum DidRejection 

pub enum DidRejection<'a> {
    Malformed,
    UnsupportedMethod(&'a str),
    EmptyMethodId,
}

Why a candidate scheme 3 value is not an admissible DID.

Three variants rather than a bool because the callers report differently: the domain has an error type per case, and a plugin turns them into one field message. Neither should have to re-derive which case it hit.

Variants

Malformed

Not did:<method>:<method-specific-id>, or the id breaks the W3C DID v1.0 clause 3.1 grammar.

UnsupportedMethod(&'a str)

Well-formed, but the method is outside the closed set clause 5 names. Carries the method as read, so a caller naming it in an error does not have to take the value apart a second time.

EmptyMethodId

A named method with nothing after it — did:web: identifies no one.
