Adds comprehensive docstrings and runnable examples to all public APIs in the `crypt`, `enchantrix`, and `trix` packages. This change is intended to bring the project's documentation to a production-ready standard and to provide high-quality, verifiable examples for the official Go documentation website.
This commit refactors the test suites for the `crypt` and `enchantrix` packages to follow the "Good, Bad, Ugly" testing methodology.
- `_Good` tests cover the ideal "happy path" scenarios.
- `_Bad` tests cover expected failure scenarios with well-formed but invalid inputs.
- `_Ugly` tests cover malicious or malformed inputs designed to cause crashes or panics.
This change improves test coverage and ensures that the codebase is more robust and resilient to unexpected inputs.
- Refactors sigil tests into a dedicated `sigils_test.go` file.
- Adds a comprehensive data-driven test for all hash sigils.
- Adds a test for error handling in the `HashSigil`.
- Adds a test for the `JSONSigil.Out` method.
- Adds tests for the error paths in the `GzipSigil.In` method.
- Fixes a bug in `GzipSigil.In` that was introduced while adding tests.
This commit introduces a new `enchantrix` package that provides a flexible and powerful way to transform data using a "Sigil" interface. The package includes implementations for various encoding types (hex, base64, gzip, json) and a comprehensive set of cryptographic hash functions.
The `trix` package has been refactored to use the new `enchantrix` package, and its API has been simplified to use string identifiers for Sigils, making it easier to use and decoupling it from the implementation details of the `enchantrix` package.
All new functionality is fully tested, and the existing tests have been updated to reflect the API changes.
