source§

impl<C: Component> Deref for WeakScope<C>

§

type Target = Rc<RefCell<Option<Scope<C>>>>

The resulting type after dereferencing.
source§

fn deref(&self) -> &Self::Target

Dereferences the value.
source§

impl<C: Component> PartialEq for WeakScope<C>

source§

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

1.0.0 · source§

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<T> Tee for T
where T: Clone,

source§

fn tee<const N: usize>(self) -> <T as TeeInternal<N>>::Output
where T: TeeInternal<N>,

Extension method to add tee() method to all T: Clone. This can’t be done directly as part of TeeInternal because it makes specifying the const param at the tee() invocation site cumbersome: TeeInternal::<N>::tee(&obj) as opposed to obj.tee::<N>(). The constraint Self: TeeInternal<N> collapses the potential impl matches to exactly 1, which makes the call to tee_internal() unambiguous. This constraint is also allowed to contain the generic parameter N because it is specified as a constraint to the method (as opposed to a constraint on the trait). I’m honestly quite surprised this works … Read more
