Trait Implementations

impl<'a> Clone for OrcReadOptions<'a>

fn clone(&self) -> OrcReadOptions<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Default for OrcReadOptions<'a>

fn default() -> Self

Returns the “default value” for a type.

impl ReadOptions<'_> for OrcReadOptions<'_>

fn to_listing_options( &self, _config: &SessionConfig, _table_options: TableOptions, ) -> ListingOptions

Helper to convert these user facing options to ListingTable options

fn get_resolved_schema<'life0, 'life1, 'async_trait>( &'life0 self, config: &'life1 SessionConfig, state: SessionState, table_path: ListingTableUrl, ) -> Pin<Box<dyn Future<Output = Result<SchemaRef>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Infer and resolve the schema from the files/sources provided.

fn _get_resolved_schema<'life0, 'async_trait>( &'a self, config: &'life0 SessionConfig, state: SessionState, table_path: ListingTableUrl, schema: Option<&'a Schema>, ) -> Pin<Box<dyn Future<Output = Result<Arc<Schema>, DataFusionError>> + Send + 'async_trait>>

where 'a: 'async_trait, 'a: 'async_trait, 'life0: 'async_trait, Self: Sync + 'async_trait,

helper function to reduce repetitive code. Infers the schema from sources if not provided. Infinite data sources not supported through this function.
