In what space? If you're talking about embedded, it's going to be pretty slow for industry to start using rust en masse. There's a huge amount of inertia in embedded, and the developers are somewhat beholden to manufacturers to release tooling around rust.

In the software space, rust is being used by quite a few companies [0].

It may be true that manufacturers are ignoring Rust but that certainly does not stop or hinder me. Tools like svd2rust mean I only need to rely on the accuracy of their svd files (industry standard register maps) - see https://github.com/rust-embedded/svd2rust

Additionally, I use vanilla VS Code and rust analyser so no need to use manufacturer supplied lock-in IDEs. There are many compiler targets to choose from for cross compilation and tools like probe-run to flash chips.

One major issue is lack of manufacturer provided code examples written in Rust. For that I rely on the Rust community. A typical example being nrf-hal for Nordic Bluetooth chips.

FWIW, the Rust embedded size also lists a few production embedded users: https://www.rust-lang.org/what/embedded
