Struct vertigo::Dependencies

pub struct Dependencies { /* private fields */ }

A graph of values and clients that can automatically compute what to refresh after one value change.

A Driver object wrapps dependency graph, so you do not need to use this under normal circumstances.

• Dependency graph holds values, computed values (computeds) and clients (render functions).
• Upon changing some value all dependent computeds get computed, and all dependent clients get rendered.
• Render function (a component) takes a computed state provided by the graph and returns a rendered element (VDomElement).
• Upon change in VDOM the real DOM is also updated.
• Components can provide the DOM with functions that get fired on events like on_click, which may modify the state, thus triggering necessary computing once again.

Trait Implementations

impl Clone for Dependencies

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for Dependencies

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq<Dependencies> for Dependencies

fn eq(&self, other: &Dependencies) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
