zig-itertools

A simple python-style generator implementation. This library models generators as a type of self-contained state coupled with a function that consumes (and may modify) the underlying state of the generator.

Benefits:

• Low overhead - Each genenrator only has struct overhead, and an additional function pointer member.

Limitations:

• This kind of mechanism would be unsafe unsafe in terms of multithreading
• Very few generators are provided by the library (so far)
• Not a true python generator, as in you can't use a yield statement to pause execution in a function, although it could be modeled.

plans:

• Full implementation of the python itertools library minus starMap and other iterators
• An eventual cleanup of the user interface, deciding between next() nextValue() and nextOptional(), and coming up with clearer names for them
• Convenience functions for making generators out of common types like slices, arrays, ArrayLists, etc.
• Testing and support for deinitialization of state data so generators can own their underlying state
