1941e9d9819c Fix unsound manipulation of env vars Martin Habovstiak <martin.habovstiak@gmail.com> parents: 22 diff changeset	5 //! Important: because of various reasons it is recommended to call the [`init`] function at

a65053246c29 Initial commit Martin Habovstiak <martin.habovstiak@gmail.com> parents: diff changeset	8 //! The goal of this crate is to make socket activation with systemd in your project trivial.
a65053246c29 Initial commit Martin Habovstiak <martin.habovstiak@gmail.com> parents: diff changeset	9 //! It provides a replacement for `std::net::SocketAddr` that allows parsing the bind address from string just like the one from `std`
a65053246c29 Initial commit Martin Habovstiak <martin.habovstiak@gmail.com> parents: diff changeset	10 //! but on top of that also allows `systemd://socket_name` format that tells it to use systemd activation with given socket name.
a65053246c29 Initial commit Martin Habovstiak <martin.habovstiak@gmail.com> parents: diff changeset	11 //! Then it provides a method to bind the address which will return the socket from systemd if available.

0 a65053246c29 Initial commit Martin Habovstiak <martin.habovstiak@gmail.com> parents: diff changeset	13 //! The provided type supports conversions from various types of strings and also `serde` and `parse_arg` via feature flag.
a65053246c29 Initial commit Martin Habovstiak <martin.habovstiak@gmail.com> parents: diff changeset	14 //! Thanks to this the change to your code should be minimal - parsing will continue to work, it'll just allow a new format.
a65053246c29 Initial commit Martin Habovstiak <martin.habovstiak@gmail.com> parents: diff changeset	15 //! You only need to change the code to use `SocketAddr::bind()` instead of `TcpListener::bind()` for binding.
