A Short Tour of C++ Modules - Modules Demystified and Applied

on YouTube ↗01h 08m

" summary

The talk explains how C++ Modules replace header files by separating module interface and implementation units, and by marking exported versus non-exported entities. It covers required compiler and build-system support, presents case studies showing large compile-time speedups and simpler dependency graphs from converting projects, and warns about cross-toolchain and per-platform issues such as template instantiation, inline/local definitions, and dual-mode library behavior that need testing and fixes.
