## Crate of the Week

<!-- COTW goes here -->
This week's crate is [embed\_it](https://github.com/riberk/embed_it), a crate that helps you to embed assets into your binary and generates structs / trait implementations for each file or directory.

Thanks to [Riberk](https://users.rust-lang.org/t/crate-of-the-week/2704/1390) for the self-suggestion!

[Please submit your suggestions and votes for next week][submit_crate]!
