From 4c7f35d09b990b0b21035144292d6556f9cc214b Mon Sep 17 00:00:00 2001 From: David Chen Date: Thu, 18 Jun 2015 12:28:02 +0000 Subject: Add initial Rust rules to Bazel. Todo: * Implement rust_bench_test for running benchmarks * Enable rust_test to depend solely on a rust_library (since many projects intermix #[test] methods in lib source). * Improve error checking and handling and prevent rust_binary from directly depending on cc_library. * Implement rust_doc for generating rustdoc. -- MOS_MIGRATED_REVID=96297772 --- examples/rust/hello_lib/BUILD | 17 +++++++++++++++++ examples/rust/hello_lib/src/greeter.rs | 31 +++++++++++++++++++++++++++++++ examples/rust/hello_lib/src/lib.rs | 15 +++++++++++++++ examples/rust/hello_lib/tests/greeting.rs | 23 +++++++++++++++++++++++ examples/rust/hello_world/BUILD | 9 +++++++++ examples/rust/hello_world/src/main.rs | 22 ++++++++++++++++++++++ 6 files changed, 117 insertions(+) create mode 100644 examples/rust/hello_lib/BUILD create mode 100644 examples/rust/hello_lib/src/greeter.rs create mode 100644 examples/rust/hello_lib/src/lib.rs create mode 100644 examples/rust/hello_lib/tests/greeting.rs create mode 100644 examples/rust/hello_world/BUILD create mode 100644 examples/rust/hello_world/src/main.rs (limited to 'examples/rust') diff --git a/examples/rust/hello_lib/BUILD b/examples/rust/hello_lib/BUILD new file mode 100644 index 0000000000..64cc935b27 --- /dev/null +++ b/examples/rust/hello_lib/BUILD @@ -0,0 +1,17 @@ +package(default_visibility = ["//visibility:public"]) + +load("/tools/build_rules/rust/rust", "rust_library", "rust_test") + +rust_library( + name = "hello_lib", + srcs = [ + "src/greeter.rs", + "src/lib.rs", + ], +) + +rust_test( + name = "greeting", + srcs = ["tests/greeting.rs"], + deps = [":hello_lib"], +) diff --git a/examples/rust/hello_lib/src/greeter.rs b/examples/rust/hello_lib/src/greeter.rs new file mode 100644 index 0000000000..be59ff888d --- /dev/null +++ b/examples/rust/hello_lib/src/greeter.rs @@ -0,0 +1,31 @@ +// Copyright 2015 Google Inc.
