Struct Db 

pub struct Db(pub SqlitePool);

A pooled SQLite connection. Cheap to clone (shares the pool handle). Queries run on rusqlite (blocking) under spawn_blocking via Db::with_conn — a deliberate choice, not a stopgap: builtins called from the (synchronous) Ling interpreter dispatch this way too, so one blocking DB layer serves both the async HTTP side and the interpreter bridge without two separate drivers.

Implementations

impl Db

pub async fn connect(path: impl AsRef<Path>) -> Result<Self>

Opens (creating if needed) a SQLite database file and returns a pool.

pub async fn connect_memory() -> Result<Self>

A private, shared-cache in-memory database — useful for tests and examples. All connections in the pool see the same data.

pub fn pool(&self) -> &SqlitePool

pub async fn with_conn<T, F>(&self, f: F) -> Result<T>

where T: Send + 'static, F: FnOnce(&Connection) -> Result<T> + Send + 'static,

Runs f against a pooled connection on a blocking thread, mapping pool/query errors into HttpError (so handlers can just ? it).

pub async fn run_migrations( &self, migrations: &'static [(&'static str, &'static str)], ) -> Result<()>

Applies (name, sql) migrations in order, skipping ones already recorded as applied in a _migrations bookkeeping table.

Trait Implementations

impl Clone for Db

fn clone(&self) -> Db

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
