Struct DefaultPub 

#[repr(transparent)]
pub struct DefaultPub<T: ?Sized>(pub T);

A wrapper for type-instances that don’t implement Publisher natively.

This structure provides an implementation of the Publisher-trait that doesn’t subscribe to anything and is therefore not alerted when the inner value changes.

Tuple Fields

0: T

Implementations

impl<T> DefaultPub<DefaultExpr<T>>

pub const fn expr_or_publisher(&self) -> DefaultPub<T>

Inherent method that is selected if the type-instance didn’t implement neither Publisher nor Expr.

The returned type doesn’t implement Expr and cannot be used to access the inner instance, leading to compile-time type errors.

Trait Implementations

impl<T: Clone + ?Sized> Clone for DefaultPub<T>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Expr> Expr for DefaultPub<T>

type Output = <T as Expr>::Output

The result type.

fn get(&self) -> Self::Output

The routine used for evaluation.

impl<T> Publisher for DefaultPub<T>

type Link = Tuple<()>

The type of the object this notifier informs.

unsafe fn subscribe(&self, _link: Pin<&Self::Link>)

Unsafely subscribes a link to the notifier.

unsafe fn unsubscribe(&self, _link: Pin<&Self::Link>)

Unsafely unsubscribes a link from the notifier.
