Trait Implementations

impl<'a> Clone for Element<'a>

fn clone(&self) -> Element<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

impl<'a> Eq for Element<'a>

impl<'a> Ord for Element<'a>

fn cmp(&self, other: &Self) -> 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<'a> PartialEq<Element<'a>> for Element<'a>

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

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