All databases implement this trait.

Required methods

fn location(&self) -> &str

Get the filepath of the database.

fn exists(&self, key: &str) -> bool

Check if a key exists in the database.

fn save<T>(&mut self, key: &str, data: &T) -> Result<(), DBError> where
    T: Deserialize<'de> + Serialize + Clone, 

Save a value of type T to the database.

fn load<T>(&mut self, identifier: &str) -> Result<T, DBError> where
    T: Deserialize<'de> + Serialize + Clone, 

Load a value of type T from the database.

fn delete(&mut self, identifier: &str)

Remove a key/value from the database.
