Cargo Features

[dependencies]
ddns-cli = { version = "0.3.3", default-features = false, features = ["default-logger", "system-alloc"] }
default = default-logger

The default-logger feature is set by default whenever ddns-cli is added without default-features = false somewhere in the dependency tree.

default-logger default = slog-envlogger, slog-stdlog
system-alloc

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.
