This makes using the tokio_unstable feature optional - the build configuration defines what is enabled, rather than the other way around. By default, and for prod builds and users who have not set a RUSTFLAGS, the tokio_unstable is enabled and this is leveraged to provide the metrics exposed by the flag. For builds where tokio_unstable is not enabled, these metrics are not included, without causing a compilation error. CI will against the flag-enabled/prod code by virtue of being the default. |
