Struct Cache 

pub struct Cache { /* private fields */ }

Maintains the autoritative list of currently trusted JWKs for a single team and caches the DecodingKey structs derived from them. Needs to be periodically seeded with latest keys by some external trigger invoking the rotate_keys() method.

Implementations

impl Cache

pub fn new(latest_key_id: &str, keymap: AccessKeyMap) -> Self

Constructs a new Cache from a key ID denoting the latest JWK and a HashMap of key IDs to AccessKey structs.

pub fn is_rotation_needed(&self, candidate_key_ids: HashSet<String>) -> bool

Given a specific map of new keys, check if an update is required.

pub fn get_latest_key_id(&self) -> String

Retrieve the latest key id

pub fn rotate_keys(&self, latest_key_id: &str, latest_keymap: AccessKeyMap)

Updates the Cache with a new latest key ID and map of AccessKey structs.

pub fn get_key_ids(&self) -> HashSet<String>

Get the current list of trusted key IDs.

pub fn get_decoding_key(&self, key_id: &str) -> Option<DecodingKey>

Attempt to retrieve a specific key as a DecodingKey struct.
