Trait ClosureFunction

pub trait ClosureFunction:
    Fn(&JsValue, &[JsValue], &mut Context, Captures) -> JsResult<JsValue>
    + DynCopy
    + DynClone
    + 'static { }

Trait representing a native built-in closure.

Closures need to have this signature in order to be callable from Javascript, but most of the time the compiler is smart enough to correctly infer the types.
