Struct mas_handlers::MetadataCache

pub struct MetadataCache { /* private fields */ }

A simple OIDC metadata cache

It never evicts entries, does not cache failures and has no locking. It can also be refreshed in the background, and warmed up on startup. It is good enough for our use case.

Implementations

impl MetadataCache

pub fn new() -> Self

pub async fn warm_up_and_run<R: RepositoryAccess>( &self, http_service: HttpService, interval: Duration, repository: &mut R, ) -> Result<JoinHandle<()>, R::Error>

Warm up the cache by fetching all the known providers from the database and inserting them into the cache.

This spawns a background task that will refresh the cache at the given interval.

pub async fn get( &self, http_service: &HttpService, issuer: &str, verify: bool, ) -> Result<Arc<VerifiedProviderMetadata>, DiscoveryError>

Get the metadata for the given issuer.
