  • Virtual Threads in Rust?
    3 projects | | 30 Sep 2022
    There’s a bunch of library-based implementations of coroutines for rust. I recall being the most interesting one, but it is quite dated. I don’t think there’s a lot of community interest in stackfull coroutines at this point.
  • Writing Rust the Elixir way
    5 projects | | 26 Nov 2020
    As we saw earlier, scheduling threads is a hard task for the operating system. To replace one thread that's being executed with another one, a lot of work needs to be done (including saving all the registers and some thread state). However, switching between Lunatic Processes does only the minimal amount of work possible. With an idea pioneered by the libfringe library and using some asm! macro magic, Lunatic lets the Rust compiler figure out the minimal number of registers to be preserved during context switches. This makes scheduling Lunatic processes zero-cost. On my machine usually 1ns, equivalent to a function call.
