Not just a pretty (inter)face.

A pretty-printer and ndjson logger for the log crate.

Examples

use kv_log_macro as log;

femme::with_level(femme::LevelFilter::Trace);
log::warn!("Unauthorized access attempt on /login");
log::info!("Listening on port 8080");

Prettified output will be displayed when debugging. In release mode, this logger will output to ndjson.

When using Wasm with #[cfg(target_arch = "wasm32")], Wasm logger will be used. Wasm logger uses web_sys crate to send console.log() to JavaScript.
