Trait Implementations

impl Clone for ExplainExecutionNodeDescriptor

fn clone(&self) -> ExplainExecutionNodeDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExplainExecutionNodeDescriptor

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

Formats the value using the given formatter.

impl PartialEq for ExplainExecutionNodeDescriptor

fn eq(&self, other: &ExplainExecutionNodeDescriptor) -> 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.
