A crate for consuming the runc binary in your Rust applications. Fully asynchronous using Futures, and Tokio.
Based on the reference go-runc implementation.
Please refer to the crate documentation.
Checkpoints rely on the external, checkpoint/restore in userspace project. The criu tool relies on a variety of kernel features and is not portable.
Due to the difficulties in shipping a criu binary for testing, and it's non portable nature, checkpoint support is currently out of scope for rust-runc.
Runc includes the ability to inherit file descriptors from a parent process. Rust's standard library does not include support for exec with additional file descriptors.
Therefore there is currently no support for preserving file descriptors.
