Function aarch64_std::thread::contribute

pub unsafe fn contribute()

This is a non-standard function that should be called by a hardware or OS thread in order to drive spawned threads.

The native thread will contribute its CPU time to the runtime’s green threads and returns if there are no green threads that currently need to be driven (at which point you may just want to call this function again).

Safety

User space threads can’t reliably detect stack overflows. Some systems have protections in place that will crash the program on overflow, but others will simply have undefined behavior. To use spawned threads safely, you must ensure that your stack sizes are big enough to never overflow.
