impl Ord for Qualifier

fn cmp(&self, other: &Qualifier) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<Qualifier> for Qualifier

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

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

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

This method tests for !=.
