pub fn init_logging()Available on crate features
test only.Expand description
Initialize global logger, using the tracing_subscriber crate, with
sensible defaults.
It is safe to call init_logging multiple times, and safe to call it in a
binary where another test has already installed a global subscriber; in
that case the installed subscriber is kept. Since cargo test does not run
tests in any particular order, each must call init_logging.
