Enum ComputeQueryId 

pub enum ComputeQueryId {
    Auto,
    Regress,
}

Semantics of the compute_query_id knob.

Variants

Auto

Production: hash + emit query id in EXPLAIN output.

Regress

Regression-test mode: elide query id from EXPLAIN output so diffs are byte-equal across runs.

Trait Implementations

impl Clone for ComputeQueryId

fn clone(&self) -> ComputeQueryId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ComputeQueryId

impl Debug for ComputeQueryId

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

Formats the value using the given formatter.

impl Default for ComputeQueryId

fn default() -> Self

Returns the “default value” for a type.

impl Eq for ComputeQueryId

impl PartialEq for ComputeQueryId

fn eq(&self, other: &ComputeQueryId) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
