An component in our virtual DOM.

Fields

tag: Tag

attrs: Attrs

style: Style

listeners: Vec<Listener<Ms>>

text: Option<String>

children: Vec<El<Ms>>

el_ws: Option<Node>

The actual web element/node

namespace: Option<Namespace>

hooks: LifecycleHooks<Ms>

empty: bool

Methods

impl<Ms> El<Ms>

pub fn empty(tag: Tag) -> Self

Create an empty element, specifying only the tag

pub fn map_message<OtherMs, F>(self, f: F) -> El<OtherMs> where
    F: Fn(Ms) -> OtherMs + Copy + 'static, 

Maps an element's message to have another message.

This allows third party components to integrate with your application without having to know about your Msg type beforehand.

Note

There is an overhead to calling this versus keeping all messages under one type. The deeper the nested structure of children, the more time this will take to run.

pub fn new_text(text: &str) -> Self

pub fn empty_svg(tag: Tag) -> Self

Create an empty SVG element, specifying only the tag

pub fn from_markdown(markdown: &str) -> Vec<Self>

Create elements from a markdown string.

pub fn from_html(html: &str) -> Vec<Self>

Create elements from an HTML string.

pub fn add_child(&mut self, element: El<Ms>)

Add a new child to the element

pub fn add_attr(&mut self, key: String, val: String)

Add an attribute (eg class, or href)

pub fn add_style(&mut self, key: String, val: String)

Add a new style (eg display, or height)

pub fn set_text(&mut self, text: &str)

Replace the element's text node. (ie between the HTML tags)

pub fn key(&self) -> Option<u32>

Shortcut for finding the key, if one exists

pub fn get_text(&self) -> String

pub fn walk_tree_mut<F>(&mut self, f: F) where
    F: FnMut(&mut Self), 

Call f(&mut el) for this El and each of its descendants
