Struct DerivedPart 

pub struct DerivedPart;

Brings the bodies the program in another file builds into the part — its parameters set as parameters says, else as its own — each entity named X there named derived(D,X) here, for the step D: a part derived from another, which follows it as it changes. Mirrored after (see MirrorPart), it is the other hand of that part, a part of its own.

Trait Implementations

impl Clone for DerivedPart

fn clone(&self) -> DerivedPart

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DerivedPart

impl Debug for DerivedPart

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

Formats the value using the given formatter.

impl Default for DerivedPart

fn default() -> DerivedPart

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DerivedPart

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Editable for DerivedPart

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

type EditingState = FormState<<DerivedPart 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 DerivedPart

fn build( model: &mut NamedModel, reader: &Reader<'_>, step: &str, args: &DerivedPartArgs, ) -> 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 DerivedPart

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

The name programs store its steps under.

type Args = <DerivedPart 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 DerivedPart

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

The file, chosen from the workspace’s programs.

const KIND: &'static str = "derived_part"

The name programs store its steps under.

const INFO: OperationInfo

type Args = DerivedPartArgs

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 new_args(_: &Context<'_>) -> DerivedPartArgs

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

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

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for DerivedPart

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
