Type Alias BoolAttribute

pub type BoolAttribute = MaybeDyn<bool>;

Type alias respresenting a possibly dynamic boolean value.

Aliased Type

enum BoolAttribute {
    Static(bool),
    Signal(ReadSignal<bool>),
    Derived(Rc<dyn Fn() -> MaybeDyn<bool>>),
}

Variants

Static(bool)

A static value.

Signal(ReadSignal<bool>)

A dynamic value backed by a signal.

Derived(Rc<dyn Fn() -> MaybeDyn<bool>>)

A derived dynamic value.

Implementations

impl<T> MaybeDyn<T>

where T: Into<MaybeDyn<T>> + 'static,

pub fn evaluate(self) -> T

where T: Clone,

Get the value by consuming itself. Unlike get_clone, this method avoids a clone if we are just storing a static value.

pub fn get(&self) -> T

where T: Copy,

Get the value by copying it.

If the type does not implement Copy, consider using get_clone instead.

pub fn get_clone(&self) -> T

where T: Clone,

Get the value by cloning it.

If the type implements Copy, consider using get instead.

pub fn track(&self)

Track the reactive dependencies, if it is dynamic.

pub fn as_static(&self) -> Option<&T>

Tries to get the value statically or returns None if value is dynamic.

Trait Implementations

impl AttributeValue for BoolAttribute

fn set_self(self, el: &mut HtmlNode, name: Cow<'static, str>)

impl<T> Clone for MaybeDyn<T>

where T: Clone + Into<MaybeDyn<T>> + 'static,

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

Returns a copy of the value.

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