Trait SelectableElement 

pub trait SelectableElement<T: HasElements<Self>>: Kind + Sized {
    const PICKED_FROM: &'static [&'static str];

    // Required method
    fn select(
        reader: &Reader<'_>,
        hit: &PickedElement,
    ) -> Option<ElementReference<T, Self>>;

    // Provided method
    fn drawn(
        reader: &Reader<'_>,
        element: &ElementReference<T, Self>,
    ) -> Vec<PickedElement> { ... }
}

A kind of element of the target T a reference field picks.

Required Associated Constants

const PICKED_FROM: &'static [&'static str]

The kinds of what an editor draws that a click picks one from (see crate::editing::hit::Scene::pick): its own kind, for an element drawn as itself.

Required Methods

fn select( reader: &Reader<'_>, hit: &PickedElement, ) -> Option<ElementReference<T, Self>>

The element a click on hit, of one of Self::PICKED_FROM, selects, read through reader: hit itself, for an element drawn as itself; none, for a hit that selects none.

Provided Methods

fn drawn( reader: &Reader<'_>, element: &ElementReference<T, Self>, ) -> Vec<PickedElement>

What an editor draws of element, to light while it is selected: the element itself, by default.

Dyn Compatibility

This trait is not dyn compatible.

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