Generic Containers in C: A Safe and Efficient vec Implementation
2025-07-26
This article details the implementation of a type- and bounds-safe generic container, `vec`, in C. `vec` is essentially a resizable array, dynamically growing using `realloc`. The author explains the implementation, including the `vec_push` function and error handling for memory allocation. Two improved interfaces, `vec_push_cap` and `vec_push_auto`, are explored for performance optimization. Bounds safety is discussed, along with interoperability with traditional C arrays via the `vec2array` macro.
