Trait Projection 

pub trait Projection {
    // Required methods
    fn name(&self) -> &str;
    fn project(
        &self,
        model: &Workbook,
        window: &Window,
        out: &mut dyn FnMut(&str),
    );
}

A projection: a pure function from the model and a window to lines, the shape every door prints (SD-23). The grid is the first (KERNEL.4), the sentence pane the second, the dependency cone drawn as a diagram the third (KERNEL.12). A projection never edits the model.

Required Methods

fn name(&self) -> &str

The projection’s name, as frazaro view selects it.

fn project(&self, model: &Workbook, window: &Window, out: &mut dyn FnMut(&str))

The window’s lines, in a fixed order, to the sink.

Dyn Compatibility

This trait is dyn compatible.

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