Cargo Features

systemd_socket = { version = "0.1.1", default-features = false, features = ["serde", "enable_systemd", "parse_arg", "tokio_0_2", "tokio_0_3", "async-std"] }
default = enable_systemd

The enable_systemd feature is set by default whenever systemd_socket is added without default-features = false somewhere in the dependency tree.

serde = serde_crate, serde_str_helpers
enable_systemd default = libsystemd
