Why Rust Broke Into TIOBE’s Top 20 – Insights from the June Rankings

The TIOBE official June programming language ranking was released, revealing that C has overtaken Java with a 17.19% share, a 1.09% lead over Java, while Rust entered the Top 20 for the first time.

Rust Enters Top 20

Rust, long praised as a reliable language, achieved a Top 20 position in the TIOBE index and was voted the most loved language in the 2020 Stack Overflow Developer Survey for the fifth consecutive year.

Since its 1.0 release in 2015, Rust has aimed to leverage multi‑core CPUs for better performance, gaining traction for its strong static typing, memory safety without a garbage collector, and adoption by tech giants such as Amazon, Facebook, Google, Twitter, and Microsoft.

Rust is a system‑level language with static strong typing that prevents runtime null‑pointer errors and performs memory management at compile time, eliminating the need for a garbage collector.

Chromium Project Considers Rust

In late May, Chromium reported that about 70% of high‑severity bugs stem from C/C++ pointer issues, prompting the project to explore safer languages like Rust to mitigate memory‑safety vulnerabilities.

Why Developers Don't Use Rust

A 2019 community survey indicated that companies avoid Rust due to steep learning curves, lacking libraries, insufficient IDE support, and the need for better training and documentation, highlighting the ecosystem's still‑growing maturity.

Other Programming Language Rankings

The article lists rankings for positions 21‑50 (non‑official, possible omissions) and provides a textual list for positions 51‑100, followed by charts showing Top 10 trends (2002‑2020), historical rankings (1985‑2020), and a “celebrity” ranking (2003‑2019).

The TIOBE index is based on the average of twelve months, using search engine queries from Google, Bing, Yahoo, Wikipedia, Amazon, YouTube, and Baidu, and while it reflects language interest, it does not directly measure actual usage.
