Struct SqliteStore 

pub struct SqliteStore { /* private fields */ }

An openEHR repository in a SQLite database.

Foreign keys are switched on explicitly

SQLite disables foreign-key enforcement by default, per connection, for backward compatibility. A store that did not enable it would accept a version pointing at a container that does not exist — and would do so silently, which is worse than not having the constraint, because the schema says it is there.

Implementations

impl SqliteStore

pub fn in_memory() -> Result<Self>

Opens an in-memory database.

Errors

Returns StoreError::Engine if SQLite cannot be opened or configured.

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

Opens a database file, creating it if absent.

Errors

Returns StoreError::Engine if the file cannot be opened.

pub fn from_connection(connection: Connection) -> Result<Self>

Wraps an existing connection.

Errors

Returns StoreError::Engine if the connection cannot be configured.

pub fn connection(&self) -> &Connection

The underlying connection, for callers that need a query this trait does not offer.
