Trait Implementations

impl Clone for Link

fn clone(&self) -> Link

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Link

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Link

fn default() -> Link

Returns the “default value” for a type.

impl PartialEq for Link

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Eq for Link

impl StructuralPartialEq for Link
