Required Methods§

Source

fn exists<K>(&self, key: K) -> bool
where K: AsRef<str>,

Source

fn clear(&mut self)

Source

fn remove<K>(&mut self, key: K) -> Result<(), RemoveError>
where K: AsRef<str>,

Source

fn load_raw<K>(&self, key: K) -> Result<Vec<u8>, LoadRawError>
where K: AsRef<str>,

Source

fn store_raw<K, V>(&mut self, key: K, value: V) -> Result<(), StoreRawError>

Provided Methods§

Source

fn load<K, T, F>( &self, key: K, format: F, ) -> Result<T, LoadError<<F as StorageFormat>::DeserializeError>>
where K: AsRef<str>, T: DeserializeOwned, F: StorageFormat,

Source

fn store<K, T, F>( &mut self, key: K, value: &T, format: F, ) -> Result<(), StoreError<<F as StorageFormat>::SerializeError>>
where K: AsRef<str>, T: Serialize, F: StorageFormat,

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
