//! Not just a pretty (inter)face.
//!
//! A pretty-printer and [ndjson](http://ndjson.org/) logger for the [log](https://docs.rs/log) crate.
//!
//! ## Examples
//! ```
//! femme::start(log::LevelFilter::Trace)?;
//! log::warn!("Unauthorized access attempt on /login");
//! log::info!("Listening on port 8080");
//! ```

/// Starts logging depending on current environment.
///
/// # Log output
///
/// - when compiling with `--release` uses ndjson.
/// - pretty-prints otherwise.
/// - works in WASM out of the box.

/// # Examples
///
/// ```
/// femme::start(log::LevelFilter::Trace).unwrap();
/// log::warn!("Unauthorized access attempt on /login");
/// log::info!("Listening on port 8080");
/// ```
