Derive Macro rusteval::Interactive

#[derive(Interactive)]

Gives interactive access to a structs fields.

What it does:

#[derive(Interactive)]
struct Struct {
    field1: u32,
    field2: u32,
}

Expands to something like:

impl Interactive for Struct {
    fn get_field<'a>(&'a self, field_name: &'a str) -> Result<'_, &dyn Interactive> {
        match field_name {
            "field1" => self.field1.try_as_interactive(),
            "field2" => self.field2.try_as_interactive(),
            _ => Err(FieldNotFound {
                type_name: "Struct",
                field_name,
            }),
        }
    }
    fn get_field_mut<'a>(&'a mut self, field_name: &'a str) -> Result<'_, &mut dyn Interactive> {
        /* ... */
    }
    fn eval_field(&self, field_name: &str, f: &mut dyn FnMut(Result<'_, &dyn Debug>)) {
        match field_name {
            "field1" => f(self.field1.try_as_debug()),
            /* ... */
        }
    }
    fn get_all_field_names(&self) -> &'static [&'static str] {
        &["field1", "field2"]
    }
}
