impl PartialEq<KeyOrIndexDisplay> for KeyOrIndexDisplay

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

This method tests for self and other values to be equal, and is used by ==.

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

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