Trait Tap4 

pub trait Tap4: Sized + Tap4Ref {
    // Provided method
    fn tap4<M, F, A1, A2, A3, A4>(
        self,
        f: F,
    ) -> impl FnOnce(A1, A2, A3, A4) -> Self
       where F: Tap4Fn<Self, A1, A2, A3, A4, M> { ... }
}

Adds by-value tap helpers for arity 4 (requires Self: Sized).

Provided Methods

fn tap4<M, F, A1, A2, A3, A4>(self, f: F) -> impl FnOnce(A1, A2, A3, A4) -> Self

where F: Tap4Fn<Self, A1, A2, A3, A4, M>,

Moves self in, calls f (which can accept &self OR &mut self), and returns self.

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.
