Struct AnyDidMethod

pub struct AnyDidMethod { /* private fields */ }

DID resolver for any known DID method.

This type regroups all the DIDMethod implementations provided by ssi into a single DIDResolver trait implementation.

Supported methods

Here is the list of DID methods currently supported by this resolver:

• did:key: for static cryptographic keys, implemented by DIDKey.
• did:jwk: for Json Web Keys (JWK) implemented by DIDJWK.
• did:web: for web-hosted DID documents, implemented by DIDWeb.
• did:pkh: implemented by DIDPKH.
• did:ethr: implemented by DIDEthr.
• did:ion: implemented by DIDION.
• did:tz: implemented by DIDTz.

Implementations

impl AnyDidMethod

pub fn new(ion: DIDION, tz: DIDTz) -> Self

Creates a new resolver using the following did:ion and did:tz method resolvers.

Use the Default implementation if you don’t want to configure DIDION and DIDTz yourself.

pub fn generate( &self, key: &JWK, method_pattern: &str, ) -> Result<DIDBuf, GenerateError>

Generate a new DID from a JWK.

The method_pattern argument is used to select and configure the DID method. Accepted patterns are

• key to generate a did:key DID,
• jwk to generate a did:jwk DID,
• ethr to generate a did:ethr DID,
• pkh:{pkh_name} to generate a did:pkh DID, where {pkh_name} should be replaced by the network id as specified by the DIDPKH::generate function.
• tz to generate a did:tz DID.

Example

use ssi_jwk::JWK;
use ssi_dids::AnyDidMethod;

// Create a DID resolver.
let resolver = AnyDidMethod::default();

// Create a JWK.
let jwk = JWK::generate_p256();

// Generate a `did:jwk` DID for this JWK:
let did = resolver.generate(&jwk, "jwk").unwrap();
