tiny::optional
A C++17 header-only drop-in replacement for std::optional that eliminates memory waste for certain types using unused bit patterns or sentinel values.
What is tiny::optional?
tiny::optional is a C++ library that serves as a memory-efficient alternative to std::optional. It solves the problem of std::optional's memory waste by storing the empty state within the payload itself using unused bit patterns or user-defined sentinel values, resulting in zero overhead for supported types.
C++ developers working on memory-sensitive applications, such as embedded systems, high-performance computing, or large-scale data processing, who need optional types without the memory bloat of std::optional.
Developers choose tiny::optional over std::optional because it provides identical functionality with significantly reduced memory usage for many common types, leading to better cache performance and lower memory footprint in critical applications.
