Title: This Week in Rust 295
Number: 295
Date: 2019-07-16
Category: This Week in Rust
Hello and welcome to another issue of *This Week in Rust*!
[Rust](http://rust-lang.org) is a systems language pursuing the trifecta: safety, concurrency, and speed.
This is a weekly summary of its progress and community.
Want something mentioned? Tweet us at [@ThisWeekInRust](https://twitter.com/ThisWeekInRust) or [send us a pull request](https://github.com/cmr/this-week-in-rust).
Want to get involved? [We love contributions](https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md).
*This Week in Rust* is openly developed [on GitHub](https://github.com/cmr/this-week-in-rust).
If you find any errors in this week's issue, [please submit a PR](https://github.com/cmr/this-week-in-rust/pulls).
# Updates from Rust Community
## News & Blog Posts

# Crate of the Week
This week's crate is [overloadable](https://crates.io/crates/overloadable), a crate to provides you with the capabilities to overload your functions in a similar style to C# or C++, including support for meta attributes, type parameters and constraints, and visibility modifiers
Thanks to [Stevensonmt](https://users.rust-lang.org/t/crate-of-the-week/2704/585) for the suggestion!
[Submit your suggestions and votes for next week][submit_crate]!

# Quote of the Week
> Rust is 5 languages stacked on top of each other, except that instead of ending up like 5 children under a trenchcoat, they end up like the power rangers.
