Struct Datums 

pub struct Datums(/* private fields */);

The datums the steps of a part added, by name.

Implementations

impl Datums

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

The datum name: one a step added, ORIGIN, or a component of a frame (see component_name) as a datum of its own.

pub fn insert(&mut self, name: &str, datum: Datum) -> GeopResult<()>

Adds datum as name: an error for a name taken.

pub fn names(&self) -> Vec<&str>

The names of the datums the steps added, sorted.

pub fn iter(&self) -> impl Iterator<Item = (&str, &Datum)>

The datums the steps added, by name, sorted.

impl Datums

pub fn draw(&self, view: &mut PartView) -> GeopResult<()>

Draws ORIGIN and every datum into view, a frame with its axes and planes each picked on its own.

Trait Implementations

impl Clone for Datums

fn clone(&self) -> Datums

Returns a duplicate of the value.

impl HasElements<AnyDatum> for Datums

const SINGLETON: Option<&'static str>

The element name, or why there is none.

fn names_target(name: &str) -> bool

impl HasElements<Point> for Datums

A point datum, or a frame by its origin.

const SINGLETON: Option<&'static str>

impl StructuralPartialEq for Datums

impl Target for Datums

Every step that adds a datum adds to them.

const CHAIN: bool = true

Whether several steps may produce a target of this type, each from what the steps before left (see crate::reader::Reader::previous): the model, the datums, the parameters’ values, the listings — what a program accumulates. A target that is not a chain — a sketch, a placed part — has one producer, and a second is an error naming both.

const KEEPER: Option<Keeper<Self>> = None

How its values are written to be kept between processes (see crate::kept): none for a target made again in every process — one that is cheap to make, or holds what cannot be written.
