Trait StorageInterfaceOpen

pub trait StorageInterfaceOpen {
    // Required methods
    fn open_or_create(
        location: &Path,
        storage_instance: u64,
    ) -> Result<Self, StorageError>
       where Self: Sized;
    fn clone_to_new_instance(&self, storage_instance: u64) -> Self;
}

Available on crate feature cara only.

Open or create a new instance of the Storage controller.

Required Methods

fn open_or_create( location: &Path, storage_instance: u64, ) -> Result<Self, StorageError>

where Self: Sized,

Initializes the current storage device.

In the case of databases, this may already result in an IO operation while when saving as files such as json folders might be created.

fn clone_to_new_instance(&self, storage_instance: u64) -> Self

Constructs a new instance from an existing one

For the case of storage_instance == 0, an instance with the same value may already exist.

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.
