v0.1.0

🎉 abin::string_view v0.1.0

Initial release of a lightweight, non-owning string view implementation for C++11 and above.

---

✨ Overview

abin::string_view is a simple, efficient alternative to std::string_view, designed for environments where C++17 is not available. It provides a familiar interface while remaining lightweight, header-only, and easy to integrate.

---

🚀 Features

• Non-owning design
  Holds only a pointer and length without managing memory.

• Zero-copy access
  Operates directly on existing string data with no additional allocations.

• Lightweight & efficient
  Minimal internal representation using const char* and size_t.

• Rich string operations
  Includes:

  • find, rfind
  • find_first_of, find_first_not_of
  • substr, compare, copy
  • starts_with, ends_with, contains

• Safe access support
  Provides bounds-checked access via at().

• Stream output support
  Compatible with std::ostream via operator<<.

• Hash support
  Includes std::hash specialization for use in unordered_map and unordered_set.

• Header-only & C++11 compatible
  No external dependencies, easy to integrate into existing projects.

---

🧪 Testing

• Fully tested using Catch2
• Verified for correctness across edge cases
• Memory-safe (no ownership, no leaks)

---

⚠️ Notes

• This implementation mimics std::string_view behavior but is designed for C++11
• As a non-owning view, users must ensure the underlying data remains valid
• Passing nullptr with non-zero length is undefined behavior

---

📦 Usage

#include "string_view.h"

abin::string_view sv = "hello world";

if (sv.starts_with("hello")) {
    std::cout << sv.substr(6) << std::endl; // world
}

---

📌 Future Improvements

• Further API alignment with C++17 std::string_view
• Additional performance optimizations
• Extended test coverage (fuzz / stress tests)
