Trait CteHost 

pub trait CteHost:
    AggregationHost
    + SubqueryHost
    + WindowHost {
    // Required methods
    fn cte_function_registry(&self) -> &FunctionRegistry;
    fn cte_execute_select(
        &self,
        statement: &SelectStatement,
        context: &ExecutionContext,
    ) -> Result<Box<dyn QueryResult>>;
}

Narrow composition contract for CTE execution. CTE materialization and inlining stay executor-owned; the host only provides the recursive SELECT entrypoint and immutable function registry.

Required Methods

fn cte_function_registry(&self) -> &FunctionRegistry

fn cte_execute_select( &self, statement: &SelectStatement, context: &ExecutionContext, ) -> Result<Box<dyn QueryResult>>

Dyn Compatibility

This trait is dyn compatible.

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