Provided Methods

fn collection_name() -> String

Return an unique name as the container for your data.

fn put_into_collection(&self, db: &DbConnection, new_key: &str) -> Result<()>

Put the object into collection with an associated key. If new_key already exits, the database will attempt to replace the offending row instead.

fn get_from_collection(db: &DbConnection, obj_key: &str) -> Result<Self>

Return the object in this collection by key.

fn del_from_collection(db: &DbConnection, obj_key: &str) -> Result<()>

Delete the object in this collection by key.

fn remove_collection(db: &DbConnection) -> Result<()>

Remove all objects in this collection.

fn list_collection(db: &DbConnection) -> Result<Vec<Self>>

List all items in the collection.

fn collection_size(db: &DbConnection) -> Result<i64>

Return the number of items in collection.

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.
