Data source trait.

Required Methods§

Source

fn schema<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Arc<Schema>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Get the schema of the data source.

Source

fn scan<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Vec<RecordBatch>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Scan the data source.

Dyn Compatibility§

This trait is dyn compatible.

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