This crate allows for the creation and usage of AF_XDP sockets on Linux, along with the attendant memory mappings and rings.

The primary difference between this crate and the other XSK/XDP crates available on crates.io is that this crate does not depend on any C code.

Why not use this crate?

This crate is still early days, and focused on the needs of Quilkin, so feature requests or bug fixes that don't pertain to it would most likely need outside contribution. There are already several other Rust crates available that (probably) have more full featured support.

Features

• - Network interface enumeration and capability querying
• - Basic Umem support
