Trait StringModel 

pub trait StringModel: Sized {
    type Message: From<Event> + Send + 'static;

    // Required methods
    fn update(&mut self, msg: Self::Message) -> Cmd<Self::Message>;
    fn view_string(&self) -> String;

    // Provided method
    fn init(&mut self) -> Cmd<Self::Message> { ... }
}

A simplified model trait that uses string-based views.

Instead of rendering directly to a Frame, implementations return a String from view_string. The string is converted to Text and rendered automatically.

This is ideal for quick prototyping and simple applications where full frame control isn’t needed.

Required Associated Types

type Message: From<Event> + Send + 'static

The message type for this model.

Required Methods

fn update(&mut self, msg: Self::Message) -> Cmd<Self::Message>

Update the model in response to a message.

fn view_string(&self) -> String

Render the view as a string.

The returned string is split by newlines and rendered into the frame. Each line is rendered left-aligned starting from the top of the frame area.

Provided Methods

fn init(&mut self) -> Cmd<Self::Message>

Initialize the model with startup commands.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
