Function bevy_internal::log::tracing_subscriber::fmt::try_init

pub fn try_init() -> Result<(), Box<dyn Error + Send + Sync>>

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()

Errors

Returns an Error if the initialization was unsuccessful, likely because a global subscriber was already installed by another call to try_init.
