Struct iota_package_resolver::PackageStoreWithLruCache

source · 
pub struct PackageStoreWithLruCache<T> { /* private fields */ }
Expand description

Store which fetches package for the given address from the backend db and caches it locally in an lru cache. On every call to fetch it checks backend db and if package version is stale locally, it updates the local state before returning to the user

Implementations§

source§

impl<T> PackageStoreWithLruCache<T>

source

pub fn new(inner: T) -> Self

source

pub fn evict(&self, ids: impl IntoIterator<Item = AccountAddress>)

Removes all packages with ids in ids from the cache, if they exist. Does nothing for ids that are not in the cache. Accepts self immutably as it operates under the lock.

Trait Implementations§
