Hyper client and server bindings for Unix domain sockets
Hyper is a rock solid Rust HTTP client and server toolkit.
Unix domain sockets provide a mechanism
for host-local interprocess communication. hyperlocal builds on and complements Hyper's
interfaces for building Unix domain socket HTTP clients.
This is useful for accessing HTTP interfaces exposed via a Unix daemons. Examples of Unix daemons that provide this kind of host local interface include Docker, a process container manager.
Add the following to your Cargo.toml file
[dependencies]
hyperlocal = "0.9"A typical server can be built by creating a tokio::net::UnixListener and accepting connections in a loop using
hyper::service::service_fn to create a request/response processing function, and connecting the UnixStream to it
using hyper::server::conn::http1::Builder::new().serve_connection().
An example is at examples/server.rs, runnable via cargo run --example server
To test that your server is working you can use an out-of-the-box tool like curl
$ curl --unix-socket /tmp/hyperlocal.sock localhost
It's a Unix system. I know this.Note that hyperlocal is not required to build a server, though hyper and tokio are both used in the example.
hyperlocal provides bindings for writing unix domain socket based HTTP clients the Client interface from the
hyper-utils crate.
An example is at examples/client.rs, runnable via cargo run --example client
Hyper's client interface makes it easy to send typical HTTP methods like GET, POST, DELETE with factory
methods, get, post, delete, etc. These require an argument that can be tranformed into a hyper::Uri.
Since Unix domain sockets aren't represented with hostnames that resolve to ip addresses coupled with network ports,
your standard over the counter URL string won't do. Instead, use a hyperlocal::Uri, which represents both file path to the domain
socket and the resource URI path and query string.
Supports hyper 1.x by providing a tower service UnixConnector and an
extension method hyper_util::client::legacy::Client::unix() to create a
client.
The server extension method bind_unix was removed since there is no longer
an equivalent to hyper::Server.
Supports hyper 0.14 and provided extensions to both hyper's Client and Server via traits.
