Trait Tuple4Map0 

pub trait Tuple4Map0<T0, T1, T2, T3> {
    // Required method
    fn map0<U>(self, f: impl FnOnce(T0) -> U) -> (U, T1, T2, T3);
}

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
