DatabaseManager

Struct DatabaseManager 

Source
pub struct DatabaseManager { /* private fields */ }
Expand description

Manages SQLite database connections

Supports multiple simultaneous database connections, each identified by a unique name derived from the file path.

§Test Isolation

  • Create new DatabaseManager instances for isolated tests
  • The global DATABASE_MANAGER is shared; use close_all() for cleanup

Implementations§

Source§

impl DatabaseManager

Source

pub fn new() -> Self

Creates a new database manager

Source

pub fn open(&self, path: &Path, create: bool) -> Result<String, SqliteToolError>

Opens or creates a database connection

If create is false and the database doesn’t exist, returns an error. If the database is already open, returns the existing connection.

Returns the database identifier (normalized path) for future reference.

Source

pub fn close(&self, name: &str) -> Result<(), SqliteToolError>

Closes a database connection

Source

pub fn get( &self, name: Option<&str>, ) -> Result<Arc<Mutex<Connection>>, SqliteToolError>

Gets a connection by name, or the default connection if name is None

Source

pub fn set_default(&self, name: &str) -> Result<(), SqliteToolError>

Sets the default database (thread-local)

Source

pub fn get_default(&self) -> Option<String>

Returns the current default database name

Source

pub fn list_open(&self) -> Vec<String>

Lists all open database connections

Source

pub fn is_open(&self, name: &str) -> bool

Checks if a database is open

Source

pub fn close_all(&self)

Closes all database connections and clears the default
