Struct PlanExecutor

Source

pub struct PlanExecutor<'d, D: OperatorTreeDriver> {
    pub driver: &'d D,
    /* private fields */
}

Expand description

Executor wrapper for OperatorTree.

Fields§

§driver: &'d D

Implementations§

Source §

impl<'d, D: OperatorTreeDriver> PlanExecutor<'d, D>

Source

pub fn new(driver: &'d D) -> Self

Source

pub fn execute(&mut self, op: &OperatorTree) -> Result<OperatorOutput, D::Error>

Execute op and capture stats. Driver failures are returned to the caller instead of being indistinguishable from an empty physical result.

Source

pub fn last_stats(&self) -> Option<&ExecutionStats>

Source

pub fn explain(&self, op: &OperatorTree) -> String
