Tracing

Tracing is a library for logging. It consists of multiple libraries. You need at least tracing, which is the base of the logging system, and tracing_subscriber, which defines the subscriber of the tracing messages.

# To install
cargo add tracing tracing_subscriber

# I recommend the use of the env filter
cargo add tracing tracing_subscriber --features env-filter

Setup

First you need to setup how the tracing messages are subscribed/used. You can setup a basic logging using the following code:

tracing_subscriber::fmt()
  .with_target(false)
  .with_level(true)
  .compact()
  .init();

# Or optional with the default env filter
tracing_subscriber::fmt()
  .with_target(false)
  .with_level(true)
  .with_env_filter(EnvFilter::default)from_default_env())
  .compact()
  .init();
