Struct SqliteDatabase 

pub struct SqliteDatabase { /* private fields */ }

An open SQLite database (file path or :memory:).

Implementations

impl SqliteDatabase

pub fn open(path: &str) -> Result<Self>

Opens a database file; :memory: for an in-memory database.

Errors

Propagates rusqlite::Error when the file cannot be opened.

pub fn in_memory() -> Result<Self>

An in-memory database (fresh per instance).

Errors

Only if SQLite cannot allocate the in-memory handle.

impl SqliteDatabase

pub fn apply_migrations( &self, module: &str, migrations: &[SqlMigration], ) -> Result<(), DbError>

Applies a module’s unapplied migrations in order, tracked under <module>/<id> in a harness_migrations table; each migration runs in its own transaction so a failure rolls back atomically and re-running is idempotent.

Errors

DbError::Batch when a migration’s SQL fails.

Panics

Only if the connection mutex is poisoned by a prior panic.
