Inherent Methods

Inherent methods are methods declared directly for a script type. They are receiver-dispatched and compile to stable method metadata when the receiver type is known.

Declaration

Use impl Type { ... } to attach methods to a script struct or enum. The first parameter is conventionally self and receives the value being called.

struct Player {
    level: i64
}

impl Player {
    fn bonus(self, amount: i64) -> i64 {
        return self.level + amount
    }
}

Calls

Method call syntax is receiver.method(args...). If the compiler knows the receiver type, it links to the resolved method. If the receiver is dynamic, runtime method dispatch resolves the target from the actual value.

fn main(player: Player) -> i64 {
    return player.bonus(5)
}

No Overloading

A type cannot define multiple methods with the same receiver/name pair. Parameter hints, defaults, and arity do not create overload sets.

Host Boundary

Registered host types can also expose methods, but those calls execute through HostAccess and registered host metadata. Script methods never expose a Rust &mut T to script code.
