Action.rs

Defines the Action enum that represents actions that can be performed by the app.

:::tip

The Action pattern is the concept of "reified method calls". You can learn a lot more about this pattern from the excellent http://gameprogrammingpatterns.com.

These are also typically called Actions or Messages.

:::note

It should come as no surprise that building a terminal user interface using ratatui (i.e. an immediate mode rendering library) has a lot of similarities with game development or user interface libraries. For example, you'll find these domains all have their own version of "input handling", "event loop" and "draw" step.

If you are coming to ratatui with a background in Elm or React, or if you are looking for a framework that extends the ratatui library to provide a more standard UI design paradigm, you can check out tui-realm for a more featureful out of the box experience.

pub enum Action {
    Tick,
    Render,
    Resize(u16, u16),
    Suspend,
    Resume,
    Quit,
    ClearScreen,
    Error(String),
    Help,
}
