| ^^^^^^^^^^^ future created by async block is not `Send`

= help: within `impl Future`, the trait `Send` is not implemented for `*const u8`
note: future is not `Send` as this value is used across an await

note: `std::ptr::null()` is later dropped here

help: consider moving this into a `let` binding to create a shorter lived borrow
