Runtime Resizable Structs in Zig

This post proposes the concept of a "runtime resizable struct" in the Zig programming language. Existing methods for handling structs with runtime-determined field lengths are cumbersome, requiring manual size calculations, memory allocation, and alignment considerations. The author presents a solution leveraging Zig's compile-time metaprogramming capabilities. Using `ResizableArray` and `ResizableStruct`, a runtime-resizable struct is implemented, simplifying operations and avoiding potential errors. The core is compile-time offset and size calculations, providing `init`, `get`, `resize`, and `deinit` methods for memory management. A minimal implementation is available on GitHub, with community feedback encouraged.
