libc++ Ranges Status

Overview

This document contains the status of the Ranges library in libc++. It is used to track both the status of the sub-projects of the ranges library and who is assigned to these sub-projects. This is imperative to effective implementation so that work is not duplicated and implementors are not blocked by each other.

If you are interested in contributing to the libc++ Ranges library, please send a message to the #libcxx channel in the LLVM discord. Please do not start working on any of the assigned items below.
