[−][src]Struct bundled_crypto::RotatingKeyStore

pub struct RotatingKeyStore<A: Algo> {
    pub algo: Arc<A>,
    pub last: Arc<A::Key>,
    pub curr: Arc<A::Key>,
}

A Send/Sync key store that keeps the last two keys.

Fields

algo: Arc<A>

A pointer to the algorithm.

last: Arc<A::Key>

A pointer to the previous key. TODO: Rename as prev.

curr: Arc<A::Key>

A pointer to the current key.

Methods

impl<K: SafeGenerateKey + Clone + Send + Sync, A: Algo<Key = K>> KeyStore<A>[src]

pub fn attempt_with_retry<T, E, F>(&self, attempt: &mut F) -> Result<T, E> where
    F: FnMut(&K, Option<E>) -> Result<T, E>, [src]

Attempt to use the current key, then the previous key. The function attempt takes in a key, and an optional result, which is populated if the first attempt fails.
