Trait DataStore

pub trait DataStore: Default + Serialize {
    // Provided methods
    fn open<P>(db: P) -> AtomicDatabase<Self>
       where P: AsRef<Path>,
             Self: DeserializeOwned { ... }
    fn open_in_memory() -> AtomicDatabase<Self>
       where Self: DeserializeOwned { ... }
    fn load(file: impl Read) -> Result<Self>
       where Self: Sized + DeserializeOwned { ... }
    fn save(&self, file: impl Write) -> Result<()> { ... }
}

This trait needs to be implemented for the Database struct. It requires a few implementations. The defined functions have default definitions.

Provided Methods

fn open<P>(db: P) -> AtomicDatabase<Self>

where P: AsRef<Path>, Self: DeserializeOwned,

Opens a Database by the specified path. If the Database doesn’t exist, this will create a new one! Wrap a Arc<_> around it to use it in parallel contexts!

fn open_in_memory() -> AtomicDatabase<Self>

where Self: DeserializeOwned,

Creates a Database instance in memory. Wrap a Arc<_> around it to use it in parallel contexts!

fn load(file: impl Read) -> Result<Self>

where Self: Sized + DeserializeOwned,

Loads file data into the Database

fn save(&self, file: impl Write) -> Result<()>

Saves data of the Database to a file

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.
