pub fn try_init() -> Result<(), Box<dyn Error + Send + Sync + 'static>>Available on crate features
fmt and std only.Expand description
Install a global tracing subscriber that listens for events and
filters based on the value of the RUST_LOG environment variable,
if one is not already set.
If the tracing-log feature is enabled, this will also install
the LogTracer to convert log records into tracing Events.
This is shorthand for
tracing_subscriber::fmt().try_init()ยงErrors
Returns an Error if the initialization was unsuccessful,
likely because a global subscriber was already installed by another
call to try_init.
