Trait Tool 

pub trait Tool: Any {
    // Required methods
    fn handle(
        &mut self,
        ctx: &mut EditorContext<'_>,
        event: &StepEditEvent,
    ) -> GeopResult<Changed>;
    fn presentation(&self) -> Presentation;

    // Provided method
    fn inspection(
        &mut self,
        _ctx: &mut EditorContext<'_>,
    ) -> GeopResult<Option<Inspection>> { ... }
}

A mode in hand while no step is edited: see the module docs. Taken in hand by its key, a fresh one each time (see crate::registry::Registry::tool).

Required Methods

fn handle( &mut self, ctx: &mut EditorContext<'_>, event: &StepEditEvent, ) -> GeopResult<Changed>

Something the user did in the viewport.

fn presentation(&self) -> Presentation

What it shows: what it would take lit, and whether a press grabs.

Provided Methods

fn inspection( &mut self, _ctx: &mut EditorContext<'_>, ) -> GeopResult<Option<Inspection>>

What it answers about the part, with every update while it is in hand: nothing, unless it says otherwise.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
