Rusty Doors

The goal of this crate is to expose the illumos Doors API in Rust. It exposes the native doors API verbatim, and also provides some moderately safer abstractions.

What are Doors?

A door is a file-like mechanism for interprocess communication, not unlike a named pipe or a UNIX Domain Socket. Client programs can invoke functions (called server procedures) in door servers if the door server has made a door available on the filesystem.

A server procedure is a function within the door server program that has a special, predefined signature. It is the entrypoint for the thread that is created (or awoken) to handle a client's door invocation.

A door server is a process that has created a door from one of its server procedures.
