Enum Node

pub enum Node<T, ATT, EVENT, MSG>
where
    MSG: 'static,
    EVENT: 'static,
    ATT: Clone,
{
    Element(Element<T, ATT, EVENT, MSG>),
    Text(Text),
}

This is the core data structure of the library. Any tree can be represented by Node. The T is generic instead of just using plain &'static str in order for this library to be used not only in html based widget but can also be used to represent native GUI widgets in various platforms.

Note: Clone is necessary for the aesthetics in the construction of node through series of function calls. Without Clone, the user code would look like these:

    div(&[class("some-class"), &[text("Some text")])

as compared to

    div([class("some-class"), [text("some text)])

Cloning is only done once, and happens when constructing the views into a node tree. Cloning also allows flexibility such as adding more children into an existing node/element.

Variants

Element(Element<T, ATT, EVENT, MSG>)

Element variant of a virtual node

Text(Text)

Text variant of a virtual node

Implementations

pub fn as_element_mut(&mut self) -> Option<&mut Element<T, ATT, EVENT, MSG>>

Get a mutable reference to the element, if this node is an element node

pub fn as_element_ref(&self) -> Option<&Element<T, ATT, EVENT, MSG>>

returns a reference to the element if this is an element node

pub fn add_children(self, children: Vec<Node<T, ATT, EVENT, MSG>>) -> Self

pub fn add_attributes_ref_mut( &mut self, attributes: Vec<Attribute<ATT, EVENT, MSG>>, )

add attributes using a mutable reference to self

pub fn get_attributes(&self) -> Vec<Attribute<ATT, EVENT, MSG>>

get the attributes of this node

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

returns the tag of this node if it is an element

pub fn text(&self) -> Option<&str>

returns the text content if it is a text node

pub fn eldest_child_text(&self) -> Option<&str>

returns the text if this node has only one child and is a text. includes: h1, h2..h6, p,

pub fn get_children(&self) -> Option<&[Node<T, ATT, EVENT, MSG>]>

return the children of this node if it is an element

Trait Implementations

impl<T: Clone, ATT, EVENT, MSG> Clone for Node<T, ATT, EVENT, MSG>

where MSG: 'static + Clone, EVENT: 'static + Clone, ATT: Clone + Clone,

fn clone(&self) -> Node<T, ATT, EVENT, MSG>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug, ATT, EVENT, MSG> Debug for Node<T, ATT, EVENT, MSG>

where MSG: 'static + Debug, EVENT: 'static + Debug, ATT: Clone + Debug,

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

Formats the value using the given formatter.

impl<T, ATT, EVENT, MSG> Display for Node<T, ATT, EVENT, MSG>

where T: ToString, EVENT: 'static, MSG: 'static, ATT: PartialEq + Ord + ToString + Clone,

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

where ATT: Clone,

fn from(v: Element<T, ATT, EVENT, MSG>) -> Self

Converts to this type from the input type.

impl<T: PartialEq, ATT, EVENT, MSG> PartialEq for Node<T, ATT, EVENT, MSG>

where MSG: 'static + PartialEq, EVENT: 'static + PartialEq, ATT: Clone + PartialEq,

fn eq(&self, other: &Node<T, ATT, EVENT, MSG>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
