Trait Renderable 

pub trait Renderable {
    // Required methods
    fn measure(&self, context: &Context) -> Measurement;
    fn render(&self, context: &Context) -> Vec<Line>;
}

Content that knows its own size and can draw itself at a width.

A container asks each child to measure, decides the child’s width, and renders the child at that width. The trait is dyn compatible, so a container can hold Box<dyn Renderable>. A reference to a widget and a Box of one are widgets too, so a container can borrow its children.

The ctl_text crate docs show a complete widget.

Required Methods

fn measure(&self, context: &Context) -> Measurement

The narrowest and widest this content can usefully be.

fn render(&self, context: &Context) -> Vec<Line>

Lines no wider than context.width(), except a word or cluster that the content’s overflow policy keeps whole.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
