Is it possible?

I have a custom `struct`

, which I want to pass to each of the functions in a vector of boxed functions ( `Vec<Box<Fn(Struct1) -> Struct2>>`

).

I tried to use Rayon (https://docs.rs/crate/rayon/1.0.3), but every time I get different errors: either `Parallelterator`

is not implemented as a trait, or there’s no `Send`

or `Sync`

implementations for the boxed functions in the vector.

If it is possible, how exactly can it be done?
