Enum Authorization 

pub enum Authorization {
    Ucan(Ucan),
    Cid(Cid),
}

An Authorization is a wrapper around something that can be resolved into a Ucan. Typically this is a Cid, but it may also be something like a Ucan itself, or a UcanIpld, or a Jwt. We don’t want to deal with each of these heterogenous types separately, so we move them around as an Authorization instead. TODO(ucan-wg/rs-ucan#32): Maybe swap this out is we get a substantially similar construct to land in rs-ucan

Variants

Ucan(Ucan)

A fully instantiated Ucan

Cid(Cid)

A Cid that refers to a Ucan that may be looked up in storage at the point of invocation

Implementations

impl Authorization

pub async fn as_ucan<S: UcanJwtStore>(&self, store: &S) -> Result<Ucan>

pub async fn as_proof_chain<S: UcanJwtStore>( &self, store: &S, ) -> Result<ProofChain>

Attempt to resolve the Authorization as a ProofChain (via its associated Ucan)
