Trait LookupSourceFactory 

pub trait LookupSourceFactory: Send + Sync {
    // Required method
    fn build<'life0, 'async_trait>(
        &'life0 self,
        config: ConnectorConfig,
        declared_schema: Option<SchemaRef>,
    ) -> Pin<Box<dyn Future<Output = Result<Arc<dyn LookupSourceDyn>, ConnectorError>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

Factory for constructing a lookup source (async, for on-demand mode).

Required Methods

fn build<'life0, 'async_trait>( &'life0 self, config: ConnectorConfig, declared_schema: Option<SchemaRef>, ) -> Pin<Box<dyn Future<Output = Result<Arc<dyn LookupSourceDyn>, ConnectorError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Build a lookup source instance from the given config.

declared_schema is the table’s declared Arrow schema, when known. Schema-bearing sources may derive their own; schemaless sources use it to project records into typed columns.

Dyn Compatibility

This trait is dyn compatible.

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