Formats the value using the given formatter. Read more

impl PartialEq for OptimizedQueryResult

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

1.0.0 (const: unstable) · 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.
