Struct Directive

pub struct Directive<T, D, P>(/* private fields */);

Custom logic that runs in the browser when the element is created or hydrated.

Trait Implementations

impl<T, P, D> Attribute for Directive<T, D, P>

where D: IntoDirective<T, P>, P: Clone + 'static, T: 'static,

const MIN_LENGTH: usize = 0usize

The minimum length of this attribute in HTML.

type AsyncOutput = Directive<T, D, P>

The type once all async data have loaded.

type State = Element

The state that should be retained between building and rebuilding.

type Cloneable = Directive<T, <D as IntoDirective<T, P>>::Cloneable, P>

An equivalent to this attribute that can be cloned to be shared across elements.

type CloneableOwned = Directive<T, <D as IntoDirective<T, P>>::Cloneable, P>

An equivalent to this attribute that can be cloned to be shared across elements, and captures no references shorter than 'static.

fn html_len(&self) -> usize

An approximation of the actual length of this attribute in HTML.

fn to_html( self, _buf: &mut String, _class: &mut String, _style: &mut String, _inner_html: &mut String, )

Renders the attribute to HTML.

fn hydrate<const FROM_SERVER: bool>( self, el: &Element, ) -> <Directive<T, D, P> as Attribute>::State

Adds interactivity as necessary, given DOM nodes that were created from HTML that has either been rendered on the server, or cloned for a <template>.

fn build(self, el: &Element) -> <Directive<T, D, P> as Attribute>::State

Adds this attribute to the element during client-side rendering.

fn rebuild(self, state: &mut <Directive<T, D, P> as Attribute>::State)

Applies a new value for the attribute.

fn into_cloneable(self) -> <Directive<T, D, P> as Attribute>::Cloneable

Converts this attribute into an equivalent that can be cloned.

fn into_cloneable_owned( self, ) -> <Directive<T, D, P> as Attribute>::CloneableOwned

Converts this attributes into an equivalent that can be cloned and is 'static.

fn dry_resolve(&mut self)

“Runs” the attribute without other side effects. For primitive types, this is a no-op. For reactive types, this can be used to gather data about reactivity or about asynchronous data that needs to be loaded.

async fn resolve(self) -> <Directive<T, D, P> as Attribute>::AsyncOutput

“Resolves” this into a type that is not waiting for any asynchronous data.

impl<T, D, P> Clone for Directive<T, D, P>

where P: Clone + 'static, D: Clone,

fn clone(&self) -> Directive<T, D, P>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T, D, P> Debug for Directive<T, D, P>

where T: Debug, D: Debug, P: Debug,

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

Formats the value using the given formatter.

impl<T, D, P> NextAttribute for Directive<T, D, P>

where D: IntoDirective<T, P>, P: Clone + 'static, T: 'static,

type Output<NewAttr: Attribute> = (Directive<T, D, P>, NewAttr)

The type of the new, combined attribute.

fn add_any_attr<NewAttr>( self, new_attr: NewAttr, ) -> <Directive<T, D, P> as NextAttribute>::Output<NewAttr>

where NewAttr: Attribute,

Adds a new attribute.

impl<T, D, P> ToTemplate for Directive<T, D, P>

const CLASS: &'static str = ""

The class attribute content known at compile time.

fn to_template( _buf: &mut String, _class: &mut String, _style: &mut String, _inner_html: &mut String, _position: &mut Position, )

Renders a view type to a template. This does not take actual view data, but can be used for constructing part of an HTML <template> that corresponds to a view of a particular type.

const TEMPLATE: &'static str = ""

The HTML content of the static template.

const STYLE: &'static str = ""

The style attribute content known at compile time.

const LEN: usize = _

The length of the template.
