Struct AddDatum 

pub struct AddDatum;

Adds a datum to the part, named by the operation’s id: a point, an axis, a plane or a coordinate system built from the selected entities by one of the Constructions. Like a sketch’s plane, it is built when the step runs and stays where it was, whatever later steps do to what it was built from.

Trait Implementations

impl Clone for AddDatum

fn clone(&self) -> AddDatum

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AddDatum

impl Debug for AddDatum

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

Formats the value using the given formatter.

impl Default for AddDatum

fn default() -> AddDatum

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AddDatum

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Operation for AddDatum

fn new_args<S: Scalar>(&self, _before: &Part<S>) -> AddDatumArgs

Nothing selected yet, and the first construction.

fn form<S: Scalar>( &self, before: &Part<S>, args: &AddDatumArgs, _: &(), ) -> Form<S>

Picking the selection, choosing among the constructions that fit it, and offsets as handles: see [crate::editor].

type Args = AddDatumArgs

Everything a step needs, as plain, serializable design data.

type Session = ()

The temporary state of editing a step beyond its arguments — () for every operation whose form says all there is to it. Starts afresh whenever an editor opens a step.

fn apply<S: Scalar>( &self, part: Part<S>, operation_id: &str, args: &AddDatumArgs, ) -> GeopResult<Part<S>>

Applies the operation as the program step operation_id, consuming part and returning the part it produces. Everything the operation creates is named after operation_id (see the crate docs), so the id has to be unique within a program.

fn set<S: Scalar>( &self, before: &Part<S>, args: &mut AddDatumArgs, _: &mut (), key: &str, value: Value, )

The field key of the form set to value: typed or chosen in the dialog, picked in the viewport, dragged as a handle.

fn event<S>( &self, before: &Part<S>, args: &mut Self::Args, session: &mut Self::Session, event: &StepEditEvent<S>, )

where S: Scalar,

A pointer or key event the editor did not take itself — a pick or a handle’s drag it does. Only an operation that draws in a canvas of its own, like a sketch, needs these.

impl PartialEq for AddDatum

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for AddDatum

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
