Trait Implementations

impl<T: Clone + Value> Clone for Observer<T>

fn clone(&self) -> Observer<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Value> Drop for Observer<T>

fn drop(&mut self)

Executes the destructor for this type.

impl<T: Value> PartialEq for Observer<T>

Implemented as pointer equality, like Rc::ptr_eq.

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