MPark.Variant
A C++17 std::variant implementation for C++11/14/17 compilers, providing type-safe unions.
What is MPark.Variant?
MPark.Variant is a C++ library that implements the C++17 `std::variant` type for compilers supporting C++11, C++14, or C++17. It provides a type-safe union container that can hold one of several alternative types, enabling modern sum type semantics in codebases that cannot yet upgrade to C++17. The library solves the problem of accessing variant features without requiring the latest compiler standard.
C++ developers working on projects constrained to C++11/14 who need type-safe union functionality, or those seeking a portable, well-tested `std::variant` implementation across multiple compiler versions.
Developers choose MPark.Variant for its strict adherence to the C++17 standard, single-header simplicity, and extensive compiler support. It is derived from the author's implementation for libc++, ensuring high-quality conformance and reliability.
