pub struct EthLogsTable { /* private fields */ }

Implementations

impl EthLogsTable

pub fn new( config: &EthProviderConfig, rpc_client: DynProvider<AnyNetwork>, ) -> Self

Trait Implementations

impl Debug for EthLogsTable

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl TableProvider for EthLogsTable

fn as_any(&self) -> &dyn Any

Returns the table provider as Any so that it can be downcast to a specific implementation.

fn table_type(&self) -> TableType

Get the type of this table for metadata/catalog purposes.

fn schema(&self) -> SchemaRef

Get a reference to the schema for this table

fn supports_filters_pushdown( &self, filters: &[&Expr], ) -> Result<Vec<TableProviderFilterPushDown>>

Specify if DataFusion should provide filter expressions to the TableProvider to apply during the scan.

fn scan<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, state: &'life1 dyn Session, projection: Option<&'life2 Vec<usize>>, filters: &'life3 [Expr], limit: Option<usize>, ) -> Pin<Box<dyn Future<Output = Result<Arc<dyn ExecutionPlan>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Create an ExecutionPlan for scanning the table with optionally specified projection, filter and limit, described below.

fn constraints(&self) -> Option<&Constraints>

Get a reference to the constraints of the table. Returns:

fn get_table_definition(&self) -> Option<&str>

Get the create statement used to create this table, if available.

fn get_logical_plan(&self) -> Option<Cow<'_, LogicalPlan>>

Get the LogicalPlan of this table, if available.

fn get_column_default(&self, _column: &str) -> Option<&Expr>

Get the default value for a column, if available.

fn scan_with_args<'a, 'life0, 'life1, 'async_trait>( &'life0 self, state: &'life1 dyn Session, args: ScanArgs<'a>, ) -> Pin<Box<dyn Future<Output = Result<ScanResult, DataFusionError>> + Send + 'async_trait>>

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

Create an ExecutionPlan for scanning the table using structured arguments.

fn statistics(&self) -> Option<Statistics>

Get statistics for this table, if available Although not presently used in mainline DataFusion, this allows implementation specific behavior for downstream repositories, in conjunction with specialized optimizer rules to perform operations such as re-ordering of joins.

fn insert_into<'life0, 'life1, 'async_trait>( &'life0 self, _state: &'life1 dyn Session, _input: Arc<dyn ExecutionPlan>, _insert_op: InsertOp, ) -> Pin<Box<dyn Future<Output = Result<Arc<dyn ExecutionPlan>, DataFusionError>> + Send + 'async_trait>>

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

Return an ExecutionPlan to insert data into this table, if supported.
