Achieving warp speed with Rust

If you're looking to write fast code in Rust, good news! Rust makes it really easy to write really fast code. The focus on zero-cost abstractions, the lack of implicit boxing and the static memory management means that even naïve code is often faster than the equivalent in other languages, and certainly faster than naïve code in any equally-safe language. Maybe, though, like most programmers you've spent your whole programming career safely insulated from having to think about any of the details of the machine, and now you want to dig a little deeper and find out the real reason that Python script you rewrote in

# Rsync based file backup script, with hard-linking enabled.

# Runtime options:
# -n - dry-run; do nothing, just display what is going to happen on a real run
# -v - verbose output; print out what is being backed up
#

# set to your rsync location
