Struct CompositeKeyResolver 

pub struct CompositeKeyResolver { /* private fields */ }

Resolvers tried in order: the first answer other than Unsupported is the answer, an error included.

Examples

use identity_kit::jose::Jwk;
use identity_kit::methods::DidKey;
use identity_kit::resolver::{CompositeKeyResolver, JwkResolver, KeyReference, KeyResolver as _, KeyRole, Resolver};

let resolver = CompositeKeyResolver::new()
    .with(Resolver::builder().with(DidKey::default()).build())
    .with(JwkResolver);

// RFC 8037 Appendix A.2.
let key: Jwk = serde_json::from_str(
    r#"{"kty":"OKP","crv":"Ed25519","x":"11qYAYKxCrfVS_7TyWQHOg7hcvPapiMlrwIaaPcHURo"}"#,
)?;
let resolved = resolver.resolve_key(&KeyReference::Jwk(Box::new(key.clone())), KeyRole::Issuer).await?;
assert_eq!(resolved, key);

Implementations

impl CompositeKeyResolver

pub fn new() -> Self

A resolver with nothing to try: every reference is unsupported.

pub fn with(self, resolver: impl KeyResolver + 'static) -> Self

This resolver trying resolver after the ones added before.

pub fn with_shared(self, resolver: Arc<dyn KeyResolver>) -> Self

This resolver trying the shared resolver after the ones added before.

pub fn len(&self) -> usize

How many resolvers it tries.

pub fn is_empty(&self) -> bool

Whether it has no resolver to try.

Trait Implementations

impl Clone for CompositeKeyResolver

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CompositeKeyResolver

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl KeyResolver for CompositeKeyResolver

fn resolve_key<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 KeyReference, role: KeyRole, ) -> Pin<Box<dyn Future<Output = Result<Jwk, KeyResolutionError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

The public key key names, usable in role.
