Implementations§

impl ExplainPlan

pub fn fingerprint(&self) -> PlanFingerprint

Compute a stable fingerprint for this explain plan.

Trait Implementations§

impl Clone for ExplainPlan

fn clone(&self) -> ExplainPlan

Returns a duplicate of the value. Read more

1.0.0 · Source§

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

Performs copy-assignment from source. Read more

impl Debug for ExplainPlan

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

Formats the value using the given formatter. Read more

impl From<ExplainPlan> for QueryDiagnostics

fn from(explain: ExplainPlan) -> Self

Converts to this type from the input type.

impl PartialEq for ExplainPlan

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

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

1.0.0 · Source§

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

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