Struct Threads 

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

A part’s cosmetic threads, by name: the value of its target threads, which every step that records one revises.

Implementations

impl Threads

pub fn add( &mut self, name: impl Into<String>, thread: CosmeticThread, ) -> GeopResult<()>

Records thread under name. Fails, leaving the threads as they are, if there is a thread of that name already.

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

Every cosmetic thread, by name.

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

The cosmetic thread name.

pub fn of_step(&self, step: &str) -> Vec<String>

The cosmetic threads the step step recorded — those named after it — by name.

impl Threads

pub fn drawn(&self, step: &str) -> GeopResult<Vec<ViewAnnotation>>

What a viewer draws of each thread the step step recorded: its name, its designation and its helix as a polyline.

Trait Implementations

impl Clone for Threads

fn clone(&self) -> Threads

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Threads

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Threads

fn default() -> Threads

Returns the “default value” for a type.

impl HasElements<Threads> for Threads

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> = &'a Threads

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

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

The element name, or why there is none.

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 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 Threads

Read whole.

const NAME: &'static str = "threads"

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

impl PartialEq for Threads

fn eq(&self, other: &Threads) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl StructuralPartialEq for Threads

impl Target for Threads

Every step that records threads 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.
