Struct SqliteConnectionPool

pub struct SqliteConnectionPool { /* private fields */ }

Available on crate feature sqlite only.

Implementations

impl SqliteConnectionPool

pub async fn new( path: &str, mode: Mode, join_push_down: JoinPushDown, attach_databases: Vec<Arc<str>>, busy_timeout: Duration, ) -> Result<Self, Error>

Creates a new instance of SqliteConnectionPool.

NOTE: The SqliteConnectionPool currently does no connection pooling, it simply creates a new connection and clones it on each call to connect().

Errors

Returns an error if there is a problem creating the connection pool.

pub async fn init(path: &str, mode: Mode) -> Result<(), Error>

Initializes an SQLite database on-disk without creating a connection pool. No-op if the database is in-memory.

pub async fn setup(&self) -> Result<(), Error>

pub fn connect_sync( &self, ) -> Box<dyn DbConnection<Connection, &'static (dyn ToSql + Sync)>>

pub async fn try_clone(&self) -> Result<Self, Error>

Will attempt to clone the connection pool. This will always succeed for in-memory mode. For file-mode, it will attempt to create a new connection pool with the same configuration.

Due to the way the connection pool is implemented, it doesn’t allow multiple concurrent reads/writes using the same connection pool instance.
