• Adding logging or println absolutely wrecks throughput of my axum server

• How does env_logger work without being importing the library?
  1 project | /r/rust | 14 Apr 2022

  I've been using env_logger for setting log-levels through environment variables, and I've been confused about something. In every example of the library, they just say call env_logger::init() before instantiating any logger, and I do that. But the weird this is that, I can call this without a use env_logger line anywhere in my module or code. I've added env_logger to the Cargo.toml file, but that shouldn't be enough to inject this module into the runtime, should it? If that is the case, how are they doing this?

  I use env_logger which allows the user to set verbosity through an environment variable. It also allows specifying which module to output logs from, or all.
