Implementations

impl DatabaseInstance

pub fn new( id: DatabaseId, name: String, path: String, owner: DatabaseOwner, ) -> Self

Create a new database instance

pub fn is_memory(&self) -> bool

Check if this is an in-memory database

pub fn refresh_schema(&mut self, conn: &Connection) -> Result<()>
