bootstrap: add wrapper macros for `feature = "tracing"`-gated `tracing` macros Follow-up to https://github.com/rust-lang/rust/pull/136091#discussion_r1930219425. - Add wrapper macros for `error!`, `warn!`, `info!`, `debug!` and `trace!`, which `cfg(feature = "tracing")`-gates the underlying `tracing` macros. They expand to nothing if `"tracing"` feature is not enabled. - This is not done for `span!` or `event!` because they can return span guards, and you can't really wrap that. - This is also not possible for `tracing::instrument` attribute proc-macro unless you use another attribute proc-macro to wrap that. It's not *great*, because `tracing::instrument` and `tracing::{span,event}` can't be wrapped this way. Can test locally with: ```bash $ BOOTSTRAP_TRACING=bootstrap=TRACE ./x check src/bootstrap/ ``` r? ``@onur-ozkan`` (or reroll) |
