All the right moves in #Rust
One of the things I love about Rust is its ownership-system. The ability to express a resource changing ownership (moving) is a huge enabler, eg. allowing to express APIs that are impossible to misuse.
I've just a found a good example: Bulletproofs are implemented in Rust, and are using move semantics to enforce secure usage.
As a side-note: it looks to me like Rust has already become a de facto standard for #crypto world infrastructure.
