Summary:
The Rust Thrift implementation presently compiles to 4 crates:
```lang=mermaid
flowchart TD;
foo --> foo-clients;
foo --> foo-types;
foo --> foo-services;
foo-clients --> foo-types;
foo-services --> foo-types;
```
Sadly, the one with the best name is the most useless. That top-level foo crate just contains the following:
```
pub use ::foo_types as types;
pub use ::foo_clients as client;
pub use ::foo_services as server;
pub use ::foo_types::consts;
pub use ::foo_types::errors;
pub use ::foo_types::services;
pub use ::foo_clients::mock;
pub use self::consts::*;
pub use self::errors::*;
pub use self::types::*;
```
Furthermore, it is extremely uncommon for anything to want to be both a client and a server of the *same* Thrift interface. It arises occasionally for proxies, but otherwise you are either implementing the server for a particular service, or accessing it as a client, not both.
I am interested in eliminating the useless crate, and renaming the types subcrate to the nice name.
```lang=mermaid
flowchart TD;
foo-clients --> foo;
foo-services --> foo;
```
### Implementation plan
1. This diff
2. Migrate everything that uses `:foo-rust` and needs a client to `:foo-rust-clients`, and everything that needs a server to `:foo-rust-services` -- after this point, everything still depending on `:foo-rust` only uses types
3. In the macros, atomically delete `:foo-rust` and rename `:foo-rust-types` into its place (this will be a small diff)
