Usage

Each module is a self-contained single file that you can copy directly into your project. No installation required.

Some modules have optional sibling dependencies on other zerodep modules (e.g. structlog can use ansi for color support). These are loaded via guarded imports — if the sibling module is absent, the module falls back to inline constants and remains fully functional.
