Struct EditorContext 

pub struct EditorContext<'a> { /* private fields */ }

The Editor, as a panel’s command, a tool or a panel told of an edit sees it: the program and what it built, and the few ways they change that the editor keeps track of — so that undo, the marker and the step being edited stay right whatever the extension does.

Implementations

impl<'a> EditorContext<'a>

pub fn program(&self) -> &Program

The program, as saved: the file edited.

pub fn part(&self) -> Reader<'_>

The part the program builds, as far as it last ran.

pub fn drawn(&self) -> Option<Visible<'_>>

The part as last drawn, but what the viewer was told not to draw: what a tool picks in.

pub fn runs(&self) -> u64

How many times the editor has run the program: what the part is built as changes only when this does.

pub fn idle(&self) -> GeopResult<()>

Refuses while a step is edited.

pub fn run_all(&mut self)

Runs the whole of the program run now: the step edited’s, or the file’s.

pub fn rerun(&mut self) -> Rerun<'_>

The program run now — the step edited’s, or the file’s — with the part as it last ran, to run again.

pub fn move_state(&mut self, moved: StateValues)

Moves the file’s state to moved, where it says.

pub fn edit_program( &mut self, edit: impl Fn(&mut Program) -> GeopResult<()>, ) -> GeopResult<()>

Edits the file — and the program of the step being edited, which then sees the edit too — by edit. The marker and the step edited stay at their steps, found again by id: an edit may move steps.

pub fn undoable(&mut self, before: Program)

Makes the file going back to before one edit to undo — what a drag of many events is — if it changed since.

pub fn inspect( &mut self, kind: &str, picked: &[PickedElement], ) -> GeopResult<Inspection>

The answer of the inspector kind about the elements picked of the part as far as it runs.
