pub trait InsertStrict<K, V>: StorageBackend {
    fn insert_strict(&self, key: &K, value: &V) -> Result<(), Self::Error>;
}
Expand description

InsertStrict<K, V> trait extends the StorageBackend with insert_strict operation for the (key: K, value: V) pair; therefore, it should be explicitly implemented for the corresponding StorageBackend.

Required Methods

Inserts the (K, V) pair in the storage without overwriting the value if it already exists.
