Struct ScaleBody 

pub struct ScaleBody;

Scales the bodies bodies — solids, and sheets by one of their faces — about the point about by factors along the world’s x, y and z: in place, every entity keeping its name. Exact: a NURBS curve or surface scaled is its control points scaled, weights and parametrization kept, so every pcurve stays as it is. Unequal factors make a circle an ellipse — exactly, as a NURBS. A negative factor mirrors (an odd number of them turns every face around, so the normals still point out); a factor of zero is refused.

Trait Implementations

impl Clone for ScaleBody

fn clone(&self) -> ScaleBody

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ScaleBody

impl Debug for ScaleBody

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

Formats the value using the given formatter.

impl Default for ScaleBody

fn default() -> ScaleBody

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ScaleBody

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Editable for ScaleBody

const INFO: OperationInfo = <ScaleBody as ::geop_core_editor::part_operation::PartOperation>::INFO

type EditingState = FormState<<ScaleBody as PartOperation>::Session>

What the editor keeps about a step while it is edited, beyond its arguments, starting from the default whenever a step is opened.

fn new_args(context: &Context<'_>) -> Self::Args

The arguments of a new step: sensible defaults, taking the part it is inserted into into account.

fn presentation( context: &Context<'_>, args: &Self::Args, editing: &Self::EditingState, ) -> Form

What the editor shows while the step is edited. Never fails: an editor needs the form most exactly when the arguments do not build, so whatever is wrong is said in it.

fn process_user_event( context: &Context<'_>, args: &Self::Args, editing: &Self::EditingState, event: Event, ) -> (Self::Args, Self::EditingState)

The step’s arguments and editing state after event.

impl ModelOperation for ScaleBody

fn build( model: &mut NamedModel, reader: &Reader<'_>, _: &str, args: &ScaleBodyArgs, ) -> GeopResult<()>

Builds the step step — what everything it makes is named after — into model, reading whatever else it builds on through reader, so the step is rebuilt when that changes.

impl Operation for ScaleBody

const KIND: &'static str = <ScaleBody as ::geop_core_editor::part_operation::PartOperation>::KIND

The name programs store its steps under.

type Args = <ScaleBody as PartOperation>::Args

What a step of the operation is given. It is saved with the program, so it names targets and elements, never holds their internal ids.

fn run(ctx: &mut StepContext<'_>, args: &Self::Args) -> __GeopResult<()>

Declares what the step produces, through ctx (see StepContext::produce): cheap, since it runs in every run. What takes work is done in the makes, which run only when what they read changed.

impl PartOperation for ScaleBody

fn new_args(context: &Context<'_>) -> ScaleBodyArgs

The newest solid, about the origin, not scaled yet.

fn form<'a>( context: &'a Context<'a>, args: &ScaleBodyArgs, _: &FormState<()>, ) -> EditForm<'a, ScaleBodyArgs>

The bodies, picked; the point scaled about and the factors.

const KIND: &'static str = "scale_body"

The name programs store its steps under.

const INFO: OperationInfo

type Args = ScaleBodyArgs

What a step is given. It is saved with the program, so it names targets and elements, never holds their internal ids.

type Session = ()

What the editor keeps while a step is edited besides its arguments and the visuals selected: () for most.

fn run(ctx: &mut StepContext<'_>, args: &ScaleBodyArgs) -> GeopResult<()>

Declares what the step produces, through ctx (see StepContext::produce).

fn begin_event(session: &mut Self::Session)

What the session forgets at the start of every event, before the event is handled: nothing, by default.

fn canvas( context: &Context<'_>, edit: Edit<'_, Self::Args, Self::Session>, event: &CanvasEvent, )

What the pointer or a key did on the canvas: nothing, by default.

impl PartialEq for ScaleBody

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for ScaleBody

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
