Debug

interface Debug

The Debug interface is used to inspect a value to help with debugging.

This will used to string interpolate the value in a debug context: {var:?}.

You can implement this interface for your own types to provide a custom debug representation.

For example:

struct User {
   name: string,
}

impl Debug for User {
   pub fn inspect(self): string {
      return `User { name: ${self.name} }`;
   }
}

let user = User { name: "Alice" };
assert_eq user.inspect(), "User { name: Alice }";
assert_eq `${user:?}`, user.inspect();
