| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In Rust 2018 edition, `extern crate` is no longer required for importing from other crates. Instead of writing: extern crate dep; use dep::Thing; we write: use dep::Thing; In this approach, macros are imported individually from the declaring crate rather than through #[macro_use]. Before: #[macro_use] extern crate sys_util; After: use sys_util::{debug, error}; The only place that `extern crate` continues to be required is in importing the compiler's proc_macro API into a procedural macro crate.

* edition: Fill in macro importsDavid Tolnay2019-04-15
| | | | | | | | | | | | | | | | | | | | Macros were previously imported through `#[macro_use] extern crate`, which is basically a glob import of all macros from the crate. As of 2018 edition of Rust, `extern crate` is no longer required and macros are imported individually like any other item from a dependency. This CL fills in all the appropriate macro imports that will allow us to remove our use of `extern crate` in a subsequent CL.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The derive(MsgOnSocket) macro used to expand to something like: const __MSG_ON_SOCKET_IMPL_Typename: () = { extern crate msg_socket as _msg_socket; impl _msg_socket::MsgOnSocket for Typename { ... } }; This was helpful in 2015 edition code by allowing callers to invoke the derive without also writing `use msg_socket` at the top of the file to bring the crate into scope.
