Explore the lesser-known features of C++20 in this comprehensive conference talk from ACCU 2022. Delve into the "small pearls" of the language update, including the spaceship operator for automatic comparison operations, enhanced compile-time programming capabilities with consteval and constinit, and improved template functionality. Learn about std::span for safe contiguous memory access, enhancements to the time library, and the new date type. Discover the power of std::format for data formatting, and explore synchronization tools like semaphores, latches, and barriers for thread coordination. Gain insights into the improved self-maintaining thread with interruption support and synchronized output streams for clean concurrent write operations. Benefit from speaker Rainer Grimm's extensive experience as a software architect, team lead, and instructor as he guides you through these valuable C++20 features.
