Tweet us at [@ThisWeekInRust](https://twitter.com/ThisWeekInRust) to get your job offers listed here!* # Crate of the Week This week's Crate of the Week is [Glium](https://github.com/tomaka/glium) a safe Rust wrapper for OpenGL. Thanks to [DroidLogician](https://users.rust-lang.org/users/DroidLogician) for the suggestion. [Submit your suggestions for next week][submit_crate]! OpenGL is a time-honored standard, which also means its API has seen enough growth to make it look like you might find Sleeping Beauty if you look deep enough. Also it was created when multi-core wasn't exactly on the radar, so many things are not thread safe. Caveat error! Glium pre-verifies whatever it can to make errors either impossible at compile time or panic before it can crash (so you at least get a helpful message instead of random garbage). It caches the context, manages your buffers using Rust's standard RAII idiom and by this brings some much-needed sanity to OpenGL programming. # Quote of the Week > S-s-s-s-stack alloc Queen, no C++ though > Might drop that pointer, no nullable though > Tell golang, "Yo, don't you got enough mem to slow?" > Tell 'em Kangaroo Rust, I'll box your flow > > Advanced pattern matching - possible > Don't go against Rusty - impossible > Runtime will leave your CPU on popsicle > Man these h*es couldn't be any less logical — [A tribute to #NickiMinaj and #rustlang by @boghison](https://twitter.com/boghison/status/653194698983669764).
