☑ Uncovering Rust: Loops and Collections

Rust is fairly new multi-paradigm system programming language that claims to offer both high performance and strong safety guarantees, particularly around concurrency and memory allocation. As I play with the language a little, I’m using this series of blog posts to discuss some of its more unique features as I come across them. This one discusses looping constructs and standard library collections.

This is the 3rd of the 7 articles that currently make up the “Uncovering Rust” series, the first of which was Uncovering Rust: References and Ownership.

☑ Hash Collision Fun

When dealing with data structures that involve hashing, most commonly hash tables, it’s fairly common knowledge that your choice of hash function is an important performance consideration. What’s perhaps less well known is that it can be an important security consideration too - this article briefly discusses why.
