mac-process

This is a divergent fork/port of libproc-rs for getting information and verifying the integrity of macOS processes that diverges from the original libproc source code.

Comparison

Focuses mainly on macOS-specific functionality, while other OSes are not supported (Linux users should use procfs, which provide a similar interface to this crate using /proc/{pid}).
Supports a higher-level construct with the help of Mach functions, libproc functions, and the kqueue API:
- The ProcessMonitor object yields shared, (practically) race-free handles to live processes.
- Process exit notifications are supported.
- To avoid race conditions due to PID reuse, dead processes cannot be queried (if they happen to be queried, the results are ignored).
All errors are converted to std::io::Error, and certain items in low-level libraries are also parsed into Rust types.
Caching of certain immutable fields is supported - this is useful when a user needs to query the same process multiple times.
Supports opening the main executable over /.vol for checking its contents (e.g. MD5 and SHA256 hashes).

More information (testing, building)

See the original repo (https://github.com/andrewdavidmackenzie/libproc-rs) for more details. Information related to Linux is not applicable in this crate.

TODO

Introduce signature verification for MacOS binaries
Implement other high-level APIs
Discuss re-merging with libproc-rs for completeness
Figure out whether custom error types are needed
