This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, __arg_0: &StabilityLevel) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl PartialEq for StabilityLevel

fn eq(&self, __arg_0: &StabilityLevel) -> bool

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

fn ne(&self, __arg_0: &StabilityLevel) -> bool

This method tests for !=.
