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.

Dyn Compatibility

This trait is dyn compatible.

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