[−][src]Struct sauron_core::dom::DomUpdater
Used for keeping a real DOM node up to date based on the current Node and a new incoming Node that represents our latest DOM state.
Fields
current_vdom: Node<MSG>
the current vdom representation
active_closures: HashMap<u32, Vec<(&'static str, Closure<dyn FnMut(Event)>)>>
The closures that are currently attached to elements in the page.
We keep these around so that they don't get dropped (and thus stop working);
node_idx_lookup: HashMap<NodeIdx, Node>
a fast lookup for getting the Node from from NodeIdx
focused_node: Option<Node>
after mounting or update dispatch call, the element will be focused
Implementations
impl<MSG> DomUpdater<MSG>
[src]
pub fn new(current_vdom: Node<MSG>, mount: &Node) -> DomUpdater<MSG>
[src]
Creates and instance of this DOM updater, but doesn't mount the current_vdom to the DOM just yet.
pub fn active_closure_len(&self) -> usize
[src]
count the total active closures regardless of which element it attached to.

MSG: 'static,

MSG: 'static,
pub fn append_to_mount<DSP>(&mut self, program: &DSP) where
DSP: Dispatch<MSG> + Clone + 'static,
[src]
DSP: Dispatch<MSG> + Clone + 'static,
Mount the current_vdom appending to the actual browser DOM specified in the root_node This also gets the closures that was created when mounting the vdom to their actual DOM counterparts.
pub fn replace_mount<DSP>(&mut self, program: &DSP) where
DSP: Dispatch<MSG> + Clone + 'static,
[src]
DSP: Dispatch<MSG> + Clone + 'static,
Mount the current_vdom replacing the actual browser DOM specified in the root_node This also gets the closures that was created when mounting the vdom to their actual DOM counterparts.
pub fn new_append_to_mount<DSP>(
program: &DSP,
current_vdom: Node<MSG>,
mount: &Element
) -> DomUpdater<MSG> where
DSP: Dispatch<MSG> + Clone + 'static,
[src]
program: &DSP,
current_vdom: Node<MSG>,
mount: &Element
) -> DomUpdater<MSG> where
DSP: Dispatch<MSG> + Clone + 'static,
Create a new DomUpdater
.
A root Node
will be created and appended (as a child) to your passed
in mount element.
pub fn new_replace_mount<DSP>(
program: &DSP,
current_vdom: Node<MSG>,
mount: Element
) -> DomUpdater<MSG> where
DSP: Dispatch<MSG> + Clone + 'static,
[src]
program: &DSP,
current_vdom: Node<MSG>,
mount: Element
) -> DomUpdater<MSG> where
DSP: Dispatch<MSG> + Clone + 'static,
Create a new DomUpdater
.
A root Node
will be created and it will replace your passed in mount
element.
pub fn update_dom<DSP>(&mut self, program: &DSP, new_vdom: Node<MSG>) where
DSP: Dispatch<MSG> + Clone + 'static,
[src]
DSP: Dispatch<MSG> + Clone + 'static,
Diff the current virtual dom with the new virtual dom that is being passed in.
Then use that diff to patch the real DOM in the user's browser so that they are seeing the latest state of the application.
pub fn patch_dom<DSP>(&mut self, program: &DSP, patches: Vec<Patch<'_, MSG>>) where
DSP: Dispatch<MSG> + Clone + 'static,
[src]
DSP: Dispatch<MSG> + Clone + 'static,
Apply patches to the dom updater Warning: only used this for debuggin purposes
pub fn map_msg<F, MSG2>(self, func: F) -> DomUpdater<MSG2> where
F: Fn(MSG) -> MSG2 + 'static,
MSG2: 'static,
[src]
F: Fn(MSG) -> MSG2 + 'static,
MSG2: 'static,
map this DomUpdater such that the Node
pub fn root_node(&self) -> Node
[src]
Return the root node of your application, the highest ancestor of all other nodes in your real DOM tree.
