    I don’t think I’ll be running rust code on an 8051 any time soon. “Microcontrollers” have sure come a long way:

    A single core ARM Cortex-M4F processor with hardware support for single precision floating point operations and a maximum clock frequency of 72 MHz.

    256 KiB of “Flash” memory. (1 KiB = 1024 bytes)

    48 KiB of RAM.

      Serious question: why not?

      My impression is that rust has a no-runtime setup , so you can get nice language features without any runtime costs

        8 and 16-bit support for AVR is actively being worked on, it already works but is still a bit buggy.
