NOTE(taiki-e): It's recommended to see #2170 (comment), if you are considering to do the same as this PR.
pin-project-lite0.2 supports enum. However, unfortunately, some enums (Either,(Try)MaybeDone) that require pin-projection used in futures-util have tuple variants and are also public APIs, so, we cannot use pin-project-lite for these enums.futures-testalso depends on pin-project, but this PR doesn't touch that as that needs support for custom Drop implementation (taiki-e/pin-project-lite#25) andfutures-testis a crate intended to be used as a dev-dependency.Closes #2170
