Struct El 

pub struct El(/* private fields */);

An html element with associated data sharing the same lifetime.

There are a number of ref_ and non-ref_ method pairs. The non-ref_ methods are chainable but consume and return the element, for use during element creation. The ref_ take a reference and as such don’t consume or return the element.

El values are clonable. Note that if you store a parent element in a child element you’ll end up with a reference cycle and the subtree will never be freed. You can use weak() to get a weak reference if you want to do this.

Implementations

impl El

pub fn text(self, text: &str) -> Self

Set text contents.

pub fn ref_text(&self, text: &str) -> &Self

pub fn id(self, id: &str) -> Self

Set the element id.

pub fn attr(self, key: &str, value: &str) -> Self

Set an arbitrary attribute. Note there are special methods for setting class and id which may afford safer workflows.

pub fn ref_attr(&self, key: &str, value: &str) -> &Self

pub fn ref_remove_attr(&self, key: &str) -> &Self

Remove an attribute from the element.

pub fn classes(self, keys: &[&str]) -> Self

Add (if not existing) all of the listed keys.

pub fn ref_classes(&self, keys: &[&str]) -> &Self

pub fn ref_remove_classes(&self, keys: &[&str]) -> &Self

Remove (if not existing) all of the listed keys.

pub fn ref_modify_classes(&self, keys: &[(&str, bool)]) -> &Self

pub fn push(self, add: El) -> Self

Add a single element to the end.

pub fn ref_push(&self, add: El) -> &Self

pub fn extend(self, add: Vec<El>) -> Self

Add multiple elements to the end.

pub fn ref_extend(&self, add: Vec<El>) -> &Self

pub fn ref_splice(&self, offset: usize, remove: usize, add: Vec<El>) -> &Self

Add and remove multiple elements.

pub fn ref_clear(&self) -> &Self

Remove all children.

pub fn own<T: 'static>(self, supplier: impl FnOnce(&El) -> T) -> Self

Attach the value to this scope, so it doesn’t get dropped until the element is removed from the tree.

pub fn ref_own<T: 'static>(&self, supplier: impl FnOnce(&El) -> T) -> &Self

pub fn on(self, event: &'static str, cb: impl FnMut(&Event) + 'static) -> Self

pub fn on_with_options( self, event: &'static str, opts: EventListenerOptions, cb: impl FnMut(&Event) + 'static, ) -> Self

pub fn ref_on( &self, event: &'static str, cb: impl FnMut(&Event) + 'static, ) -> &Self

pub fn ref_on_with_options( &self, event: &'static str, opts: EventListenerOptions, cb: impl FnMut(&Event) + 'static, ) -> &Self

pub fn on_resize(self, cb: impl Fn(El, f64, f64) + 'static) -> Self

Adds a resize callback via ResizeObserver. The callback is called on a resize with the element’s first block’s inline and block size as arguments (width and height for row layout, height and width for column layout).

pub fn ref_on_resize(&self, cb: impl Fn(El, f64, f64) + 'static) -> &Self

pub fn ref_listen( &self, event: &'static str, cb: impl FnMut(&Event) + 'static, ) -> &Self

Add a listener for an event. The listener will be detached when this element is dropped (removed from the tree).

pub fn ref_replace(&self, other: Vec<El>)

Replace the element in its parent with zero or more new elements.

pub fn raw(&self) -> Element

Get the wrapped web_sys element from the El.

pub fn ptr_id(&self) -> usize

For debugging, an id based on pointer address

pub fn weak(&self) -> WeakEl

Produce a weak reference to the element.

Trait Implementations

impl Clone for El

fn clone(&self) -> El

Returns a duplicate of the value.

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

Performs copy-assignment from source.
