Rust Hyper HTTP Library Will Contribute to Make Curl Safer
Written in C, the popular curl and libcurl tools, which are installed in some six billion devices worldwide, are exposed to well-known security problems arising from the use of a non-memory safe language. A new initiative now aims to provide a memory-safe HTTP/HTTPS backend for curl based on Rust Hyper library.

Apple Open Sources System, Swift Library Interfacing with System-Level API
System is a low-level library Apple introduced at its last WWDC conference to provide an idiomatic and type-safe interface to system calls and currency types usually available at the OS level. In keeping with Apple's aim to push Swift as a cross-platform development ecosystem, System has been open-sourced to make it easier for programmers to contribute to its further development across platforms.
