Struct vertigo::Dependencies

source ·
pub struct Dependencies { /* private fields */ }
Expand description

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

A Driver object wraps 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 (DomElement).
  • 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.
