Struct AnyDatum 

pub struct AnyDatum;

A datum of the part, whatever it is.

Trait Implementations

impl HasElements<AnyDatum> for Datums

const SINGLETON: Option<&'static str>

The name of the one target of this type a part has, if it has only one — the topology, say: a reference into it is saved as the element’s name alone.

type Element<'a> = Datum

What an element resolves to: a borrow of it, or what it gives.

fn undefined() -> Option<&'static Self>

What the target reads as where no step made it, if it reads as anything then — the datums every part starts with. None by default: reading it fails.

fn element(&self, name: &str) -> GeopResult<Datum>

The element name, or why there is none.

fn names_target(name: &str) -> bool

Whether the target named name could be one of this type: what tells a pick of an element of it from one of a target of another type with elements of the same kind (ElementReference::from_picked). The singleton’s name, for a singleton; any name, by default.

impl Kind for AnyDatum

const NAME: &'static str = drawn::DATUM

The kind’s name, as a pick says what it picked: "edge".

impl SelectableElement<Datums> for AnyDatum

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.

fn select( reader: &Reader<'_>, hit: &PickedElement, ) -> Option<ElementReference<Datums, 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.

fn drawn( _: &Reader<'_>, element: &ElementReference<Datums, Self>, ) -> Vec<PickedElement>

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