Struct DatabaseRegistry 

pub struct DatabaseRegistry { /* private fields */ }

Registry managing shared database instances.

When a connection requests a database by name, the registry either returns an existing shared instance or creates a new one. This ensures all connections to the same database name share the same data.

Implementations

impl DatabaseRegistry

pub fn new() -> Self

Create a new empty database registry.

pub async fn get_or_create(&self, name: &str) -> SharedDatabase

Get or create a shared database instance for the given name.

If a database with the given name already exists, returns a clone of its shared handle. Otherwise, creates a new database and returns it.

pub async fn get(&self, name: &str) -> Option<SharedDatabase>

Get a shared database instance if it exists.

Returns None if no database with the given name exists.

pub async fn list_databases(&self) -> Vec<String>

List all database names in the registry.

pub async fn database_count(&self) -> usize

Get the number of databases in the registry.

pub async fn register_database(&self, name: &str, db: Database)

Register a pre-built database instance.

This is useful for benchmarks where the database is pre-loaded with data before starting the server.
