* Head off imminent breakage due to https://github.com/rust-lang/rust/pull/51285.
* Fix examples and documentation to use a recently-gated feature, `proc_macro_path_invoc`.
* Update dependency versions.
By allowing unreachable patterns, we don't have to have 'NotIrrefutable' variants in the Request, Response, and Error enums.
This commit also removes an unused macro in an example.
* Create a directory for the `future::server` module, which has become quite large. server.rs => server/mod.rs. Server submodules for shutdown and connection logic are added.
* Add fn thread_pool(...) to sync::server::Options
* Configure idle threads to expire after one minute
* Add tarpc::util::lazy for lazily executing functions. Similar to `futures::lazy` but useful in different circumstances. Specifically, `futures::lazy` typically requires a closure, whereas `util::lazy` kind of deconstructs a closure into its function and args.
* Remove some unstable features, and `cfg(plugin)` only in tests. Features `unboxed_closures` and `fn_traits` are removed by replacing manual Fn impls with Stream impls. This actually leads to slightly more performant code, as well, because some `Rc`s could be removed.
* Fix tokio deprecation warnings. Update to use tokio-io in lieu of deprecated tokio-core items. impl AsyncRead's optional `unsafe fn prepare_uninitialized_buffer` for huge perf wins
* Add debug impls to all public items and add `deny(missing_debug_implementations)` to the crate.
* Bump tokio core version.
The merge of rust-lang/rust#40043 removes parse_ty_path in the latest
nightly, which we depended on. This patch rewrites that code path using
parse_path, and in the process eliminates an unreachable!() if let arm.
0 is a sentinel value used to make all enums refutable. This is a hack around issues in maros
where you're unknowingly treating irrefutable patterns as refutable, which is unfortunately
a hard error.
The server panics if it ever encountered the 0-variant, which before this patch was possible. Now,
it's not possible, because 0-variants are now not able to be deserialized.
Since rust-lang/rust#40346 has now been merged, Attribute no longer has
a .value field. Instead, we must follow the token stream and modify the
tokens directly. For Docstring attributes, there should only be one
token, the docstring value.
Unfortunately, cargo's semantic versioning gets confused by the
"-alpha" suffix in current bincode versions (I think): even though
tarpc's Cargo.toml specified version "1.0.0-alpha4", cargo will
download the more recent "1.0.0-alpha6", which has breaking changes
to the `SizeLimit` enum.
This change makes tarpc work with bincode 1.0.0-alpha6 and updates the
dependency.
