Creates a new green thread.
The returning value of the closure will be available as #value
of the thread
Examples
use rutie::{Fixnum, Thread, VM}; Thread::new(|| { let computation_result = 1 + 2; Fixnum::new(computation_result) });
Ruby:
Thread.new do
computation_result = 1 + 2
computation_result
end
pub fn call_without_gvl<F, R, G>(func: F, unblock_func: Option<G>) -> R where
F: 'static + FnOnce() -> R,
G: 'static + FnOnce(),
[src]
pub fn call_without_gvl<F, R, G>(func: F, unblock_func: Option<G>) -> R where
F: 'static + FnOnce() -> R,

Release GVL for current thread.
Warning! Due to MRI limitations, interaction with Ruby objects is not allowed while GVL is released, it may cause unexpected behaviour. Read more at Ruby documentation
You should extract all the information from Ruby world before invoking
thread_call_without_gvl
.
GVL will be re-acquired when the closure is finished.
Examples
#[macro_use] extern crate rutie; use rutie::{Class, Fixnum, Object, Thread}; class!(Calculator); methods!( Calculator, itself, fn heavy_computation() -> Fixnum { let computation = || { 2 * 2 }; let unblocking_function = || {}; // release GVL for current thread until `computation` is completed let result = Thread::call_without_gvl( computation, Some(unblocking_function) ); // GVL is re-acquired, we can interact with Ruby-world Fixnum::new(result) } ); fn main() { Class::new("Calculator", None).define(|itself| { itself.def("heavy_computation", heavy_computation); }); }
