Google says that the number of memory safety vulnerabilities has dropped considerably over the past few years/releases. They believe Android’s ongoing shift from memory-unsafe to memory-safe languages is a major factor.

There is a strong correlation between the use of Rust and the decrease in vulnerabilities found. Note that correlation is not causation, but there is strong evidence like:

To date, there have been zero memory safety vulnerabilities discovered in Android’s Rust code.

A well-known port scanner is Nmap (Network mapper). Did you know there is a (faster) Rust alternative called RustScan? To be fair it uses Nmap under the hood but utilizes multiple threads to speed up scanning.

The well-maintained repository of RustScan can be found here.

You can run Rustscan also in a Docker image. This was done to make performance consistent across different Operating Systems, because of the high open file limit.

Using a Docker in your Rust development is not new. There is an official Rust image.

A funny crate and a nice way to close the Newsletter.

The Rust Book also called The Book has now I crate of its own. This book is the starting point to learn Rust. Hiro created a command line utility to easily access the book from your command line.
