Show HN: Macro-template, table-driven code generation for Rust

- Macro-template is a Rust library that generates repetitive Rust code at compile time using a table-driven approach (think CSV-like data structures that expand into function definitions, trait impls, match arms, etc.) - It aims to reduce boilerplate without requiring users to write full procedural macros, which are notoriously complex and hard to maintain in Rust - The project is by "fast" (likely the GitHub user or org), published as a "Show HN" — a community showcase on Hacker News where makers share side projects for feedback - Table-driven code generation means you define a data table (rows/columns) and a template for each row; the macro expands each row into the corresponding code pattern, useful for things like enum-to-string conversion, command parsing, or register maps - This sits in the ecosystem alongside existing Rust macro tools like `paste`, `seq_macro`, and `phf_codegen`, but offers a distinct declarative, table-first approach
