Enum mt_dom::Node

pub enum Node<NS, TAG, ATT, VAL, EVENT> where
    NS: PartialEq + Clone + Debug,
    TAG: PartialEq + Clone + Debug,
    ATT: PartialEq + Clone + Debug,
    VAL: PartialEq + Clone + Debug,
    EVENT: PartialEq + Clone + Debug,  {
    Element(Element<NS, TAG, ATT, VAL, EVENT>),
    Text(Text),
}

represents a node in a virtual dom A node could be an element which can contain one or more children of nodes. A node could also be just a text node which contains a string

Much of the types are Generics

NS - is the type for the namespace, this will be &’static str when used in html based virtual dom implementation TAG - is the type for the element tag, this will be &’static str when used in html based virtual dom impmenentation ATT - is the type for the attribute name, this will be &’static str when used in html based virtual dom implementation VAL - is the type for the value of the attribute, this will be String, f64, or just another generics that suits the implementing library which used mt-dom for just dom-diffing purposes

Variants

Element

pub fn is_text(&self) -> bool

returns true if this a text node

pub fn take_element(self) -> Option<Element<NS, TAG, ATT, VAL, EVENT>>

consume self and return the element if it is an element variant None if it is a text node

pub fn as_element_mut(
    &mut self
) -> Option<&mut Element<NS, TAG, ATT, VAL, EVENT>>

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

pub fn as_element_ref(&self) -> Option<&Element<NS, TAG, ATT, VAL, EVENT>>

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

pub fn add_children(self, children: Vec<Node<NS, TAG, ATT, VAL, EVENT>>) -> Self

Consume a mutable self and add a children to this node it if is an element will have no effect if it is a text node. This is used in building the nodes in a builder pattern

pub fn add_children_ref_mut(
    &mut self,
    children: Vec<Node<NS, TAG, ATT, VAL, EVENT>>
)

add children but not consume self

pub fn add_attributes(
    self,
    attributes: Vec<Attribute<NS, ATT, VAL, EVENT>>
) -> Self

add attributes to the node and returns itself this is used in view building

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

add attributes using a mutable reference to self

pub fn get_attributes(&self) -> Option<&[Attribute<NS, ATT, VAL, EVENT>]>

get the attributes of this node returns None if it is a text node

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

returns the tag of this node if it is an element otherwise None if it is a text node

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

returns the text content if it is a text node

pub fn get_children(&self) -> Option<&[Node<NS, TAG, ATT, VAL, EVENT>]>

return the children of this node if it is an element returns None if it is a text node

pub fn children_mut(&mut self) -> Option<&mut [Node<NS, TAG, ATT, VAL, EVENT>]>

return the children of this node if it is an element returns None if it is a text node

pub fn node_count(&self) -> usize

recursive count the number of nodes under this tree

pub fn set_attributes_ref_mut(
    &mut self,
    attributes: Vec<Attribute<NS, ATT, VAL, EVENT>>
)

remove the existing attributes and set with the new value

pub fn merge_attributes(
    self,
    attributes: Vec<Attribute<NS, ATT, VAL, EVENT>>
) -> Self

merge to existing attributes if the attribute name already exist

pub fn get_attribute_value(&self, name: &ATT) -> Option<Vec<&VAL>>

returh the attribute values of this node which match the attribute name name
