Understanding no_std

Understanding no_std

Embedded microcontrollers lack operating system services like virtual memory, filesystems, and threads. In embedded Rust, programs declare #![no_std], compiling without the standard library while retaining the core language and primitives.

// #![no_std]
// #![no_main]
//
// use core::panic::PanicInfo;
//
// #[panic_handler]
// fn panic(_info: &PanicInfo) -> ! {
//     loop {}
// }
