Implementations

impl SharedCache

pub fn new(max_items: u32) -> Self

Instantiate a new shared cache.

pub const fn max_items(&self) -> u32

Maximum number of items that can be stored in the cache.

pub fn put(&self, key: B256, value: String) -> TransportResult<bool>

Puts a value into the cache, and returns the old value if it existed.

pub fn get(&self, key: &B256) -> Option<String>

Gets a value from the cache, if it exists.

pub fn get_deserialized<T>(&self, key: &B256) -> TransportResult<Option<T>>

where T: for<'de> Deserialize<'de>,

Get deserialized value from the cache.

pub fn save_cache(&self, path: PathBuf) -> TransportResult<()>

Saves the cache to a file specified by the path. If the files does not exist, it creates one. If the file exists, it overwrites it.

pub fn load_cache(&self, path: PathBuf) -> TransportResult<()>

Loads the cache from a file specified by the path. If the file does not exist, it returns without error.
