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<FrRepr> for FrRepr

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

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

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

This method tests for !=.

impl PartialOrd<FrRepr> for FrRepr

fn partial_cmp(&self, other: &FrRepr) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]fn lt(&self, other: &Rhs) -> bool
