I'm ignorant about Rust, but to me it's just static type language akin to C#. And C# has IOT library which seems to target Rust most usual use case, namely on embedded platform. C# also has memory safety just like Rust.

So why do we need Rust at all? What's the use case for it?

Anything that I'm missing?

C# is garbage collected. This is a no-go in many/most embedded software applications.

C# also grants you poor explicit control over heap/stack allocation: this is essential for embedded development.

I would argue that using JSON in embedded, especially on ESP32, is another no-go. I'd wage that using a binary format and later on, after you're out of ESP32, convert it to JSON would be a bigger performance gain than the evangelic tone of this article vis-a-vis of Rust.
