Trait Approver 

pub trait Approver:
    Send
    + Sync
    + Debug {
    // Required method
    fn ask(&self, p: &Presentation) -> Answer;

    // Provided methods
    fn answer(&self, question: &str) -> Option<String> { ... }
    fn via(&self) -> String { ... }
}

Asks a person, synchronously, while an attempt waits (a terminal prompt in the CLI, a permission request in an editor). The answer is journaled; replay never asks again.

Required Methods

fn ask(&self, p: &Presentation) -> Answer

The person’s answer to the presented call.

Provided Methods

fn answer(&self, question: &str) -> Option<String>

The person’s free-text answer to a question a hosted skill asks ; None when nobody can answer.

fn via(&self) -> String

Through what the person answers: terminal, or editor <name>.

Dyn Compatibility

This trait is dyn compatible.

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