Trait Implementations

impl Clone for CFRunLoopObserverContext

fn clone(&self) -> CFRunLoopObserverContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CFRunLoopObserverContext

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

impl Encode for CFRunLoopObserverContext

Available on crate feature objc2 only.

const ENCODING: Encoding

The Objective-C type-encoding for this type.

impl PartialEq for CFRunLoopObserverContext

fn eq(&self, other: &CFRunLoopObserverContext) -> 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.
