Expand description

Supplies per-query LineageContext. Implemented by the host integration.

Required Methods§

Source

fn context<'life0, 'life1, 'async_trait>( &'life0 self, session_state: &'life1 SessionState, ) -> Pin<Box<dyn Future<Output = LineageContext> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Returns the LineageContext for a query, given its session state.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
