Feasibility

How hard is it to write fast enough Rust code?

• Advent of Code Anecdote (Dumb algorithm worked)
• Rewrite Anecdote (Kotlin four times slower)
• Clippy will help
• Use references where possible
• Stay clear from tricks to achieve perfect code
• Use compile time flags before runtime injection
• Put performance testing also into the deployed binary
• Fearless mutation (mut)
• Fearless parallelism (Rayon)
