STC is a generic, type-safe, high-performance container and algorithm library for C99/C11, providing strings, vectors, maps, sets, deques, lists, smart pointers, bitsets, spans, coroutines, and random numbers via macro-based templates. It aims to bring modern ergonomics from languages like Rust, Zig, and C++ to C with minimal boilerplate.

Use cases

• use hash maps and sets in C without writing boilerplate
• get a type-safe dynamic array or vector in C99
• add coroutines with structured concurrency to a C program
• replace C++ STL containers in a pure C codebase
• use smart pointers and reference counting in C
• do regex matching on UTF-8 strings in C
• slice multi-dimensional arrays like numpy in C

When to choose

• you write C99/C11 and want modern, fast, type-safe data containers
• you need maps, sets, deques, or strings without external dependencies
• you want coroutines or smart pointers in plain C
• performance and low overhead matter more than ABI-stable prebuilt libraries

When to avoid

• your project requires a stable, frozen API before the V6.0 final release
• you prefer C++ STL or a language with native generics
• you dislike macro-heavy templating in C codebases
