Struct Update 

pub struct Update {
    pub error: Option<String>,
    pub program: Option<ProgramState>,
    pub scene: Option<SceneState>,
    pub step: Option<StepState>,
    pub files: Option<Vec<File>>,
    pub written: Option<Vec<File>>,
    pub export: Option<Export>,
    pub tool: Option<Presentation>,
    pub inspection: Option<Inspection>,
    pub lit: Option<Lighting>,
    pub report: Option<Report>,
}

What an editor shows after a command. What did not change since the last update is left out.

Fields

error: Option<String>

Why the command was refused, if it was: then it changed nothing.

program: Option<ProgramState>

scene: Option<SceneState>

step: Option<StepState>

The step being edited; None if there is none.

files: Option<Vec<File>>

The program files the command added, the one now edited first.

written: Option<Vec<File>>

The program files besides the one edited the command changed — a step of a placed part committed to its file — for the front end to keep: none if it changed none.

export: Option<Export>

The file Command::Export wrote, or Command::Copy copied.

tool: Option<Presentation>

What the tool in hand shows, while no step is edited: the drag tool’s part it would drag lit, and whether a press grabs it; the pick tool’s picks, and what the answer about them draws.

inspection: Option<Inspection>

The answer of the tool in hand about the part — the pick tool’s inspector’s about its picks — or the answer to Command::Inspect.

lit: Option<Lighting>

What to draw lit, of the part drawn and of its placed parts, when it changed (see crate::view::lit::Lighting): what the step or the tool lights and what Command::Light does. A viewer keeps it until it is sent again.

report: Option<Report>

What Command::Report asked for.
