Implementations

impl QueryTrace

pub fn scan() -> Self

Stub default: scan-labeled trace with no plan data. The no-op writes this everywhere. Impl must replace construction sites with real plan inspection.

Trait Implementations

impl Clone for QueryTrace

fn clone(&self) -> QueryTrace

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryTrace

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

Formats the value using the given formatter.

impl Default for QueryTrace

fn default() -> QueryTrace

Returns the “default value” for a type.
