Description

I tried copy and pasting this file into a new cargo project and adding tracing, tracing-subscriber and tracing-fmt to my Cargo.toml but it would not compile.

Existing example use statements

---

use tracing_fmt::format;
use tracing_subscriber::prelude::*;

Proposed use statements

---

use tracing_subscriber::fmt::format;
use tracing_subscriber::prelude::*;
use tracing_subscriber::FmtSubscriber;

Thanks! I think the example should also be moved to https://github.com/tokio-rs/tracing/tree/master/examples/examples
