Trait rusteval::Interactive

    fn get_field<'a>(
        &'a self,
        field_name: &'a str
    ) -> Result<'a, &dyn Interactive> { ... }

    ) { ... }
    fn get_all_field_names(&self) -> &'static [&'static str] { ... }
}

A trait that gives interactive access to its fields as dyn Interactive or dyn Debug.

This trait gets implemented automatically when you derive it with Interactive. See the macros documentation for more information.

Provided Methods

fn get_field<'a>(&'a self, field_name: &'a str) -> Result<'a, &dyn Interactive>

Looks for a field with the given name and on success return a shared reference to it.

fn get_field_mut<'a>(
    &'a mut self,
    field_name: &'a str
) -> Result<'a, &mut dyn Interactive>

Looks for a field with the given name and on success return a mutable reference to it.

fn eval_field(&self, field_name: &str, f: &mut dyn FnMut(Result<'_, &dyn Debug>))

Looks for a field with the given name, and passes it as a Ok(&dyn Debug) to the given closure.

On error the Err(InteractiveError) is passed to the closure instead.

fn get_all_field_names(&self) -> &'static [&'static str]

Returns all interactive field names of this type.

Can be used to drive auto-completion in a CLI.
