About:
span-lite provides a C++20 std::span implementation for C++98/11/14/17 projects. It offers a type-safe, non-owning view over contiguous sequences of objects. This single-file header-only library enables modern bounds-safe pointer interfaces without requiring a full C++20 standard library.

Key Features:

Single-file header-only library
Backwards compatible with C++98 and later
Feature detection and configuration via preprocessor macros
Provides non-owning view of contiguous memory
Zero runtime overhead abstraction

Use Cases:

Adding span-based APIs to legacy C++ codebases
Creating bounds-safe interfaces for raw pointers and arrays
Preparing code for future migration to C++20 std::span

Alternatives:

gsl::span – Microsoft's GSL includes span but requires linking to the GSL library
C++20 std::span – Native standard library solution, but requires modern compiler support
