Cargo Features

[dependencies]
panik = { version = "0.2.0", default-features = false, features = ["use-log", "use-slog", "use-stderr", "use-parking-lot"] }
default = use-log

The use-log feature is set by default whenever panik is added without default-features = false somewhere in the dependency tree.

use-log default = log
use-slog = slog, slog-stdlog
use-stderr
use-parking-lot = parking_lot

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
