fibers_zig - Dynamic Stackless Fibers for Zig
( Heap-allocated State Machine )

zig 0.14.1
tested on (l)ubuntu 22.04 LTS

zig build-exe ./src/factorial_cruncher.zig -O ReleaseFast -femit-bin=factorial_cruncher
./factorial_cruncher

there are two implementations - versions with and without POSIX Sockets support

.

factorial_cruncher.zig example uses fibers1.zig - implementation without POSIX Sockets support -
do not spend a bit more RAM when that really no needs (see fibers2.zig for version with POSIX Sockets)
