It should be noted that this implementation has been in production since last Summer and is powering the Firewall Rules ( https://blog.cloudflare.com/how-we-made-firewall-rules/ ) engine today.

This was one of the first major components to use Rust at our edge and we've been really happy with it.

The flexibility this approach (to matching traffic) has given us... whilst we also get the speed, memory safety... is just great. The speed at which we're iterating on the firewall and other systems that use this is a joy to behold. A lot of that speed derives from the confidence in this component.

We're also really pleased that whilst we have several proposals for optimisations, none have yet needed to be prioritised as the performance is great.
