Trait DidResolver 

pub trait DidResolver: Send + Sync {
    // Required method
    fn resolve(&self, did: &str) -> Result<ResolvedDid, DidResolverError>;
}

Resolves a Decentralized Identifier (DID) to its cryptographic material.

Implementations handle specific DID methods (did:key, did:keri) and return the resolved public key along with method-specific metadata. The resolver abstracts away the underlying storage and network access needed for resolution.

Args:

• did: A DID string (e.g., "did:keri:EABC..." or "did:key:z6Mk...").

Usage:

use auths_core::signing::DidResolver;

fn verify_attestation(resolver: &dyn DidResolver, issuer_did: &str) -> bool {
    match resolver.resolve(issuer_did) {
        Ok(resolved) => {
            let public_key = resolved.public_key();
            // use public_key for signature verification
            true
        }
        Err(_) => false,
    }
}

Required Methods

fn resolve(&self, did: &str) -> Result<ResolvedDid, DidResolverError>
