Yewtil#

Yewtil is a collection of common utilities that help you build applications using Yew. It includes:

  • NeqAssign - This is described in more detail in the section on optimizations and best practices and ensures that identical sets of props don't cause a component to re-render.

  • PureComponents - Components that don't update any of their state. Using NeqAssign under the hood, they act as memoized functions that are called from inside the html! macro like normal components are.

  • Lrc - linked list reference counted smart pointer functions like Rc does, but allows for novel data update patterns.

  • Mrc/Irc - Mutable/Immutable reference counted smart pointers that function like Rc but are more ergonomic to use

    within Yew, because they implement DerefMut and BorrowMutfor Mrc. This allows Mrc to be used with NeqAssign.

    Irc acts as an immutable view of the data, which makes this ideal for holding data used in display-only tasks.

  • History - A history tracking wrapper that uses a VecDeque to hold on to previous values that it has represented.

  • Futures - Support for running futures that send messages to component update loops.

  • Fetch - A wrapper around web_sys to make HTTP requests.
