Trait Implementations

impl BitOr for Change

type Output = Change

The resulting type after applying the | operator.

fn bitor(self, rhs: Change) -> Self::Output

Performs the | operation.

impl BitOrAssign for Change

fn bitor_assign(&mut self, rhs: Change)

Performs the |= operation.

impl Clone for Change

fn clone(&self) -> Change

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Change

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

Formats the value using the given formatter.

impl PartialEq for Change

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

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

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 Copy for Change

impl StructuralPartialEq for Change
