tldhax 0.0.3

TLD registration rule checker

tldhax

tldhax is a Rust library with Python bindings for checking whether a candidate domain could be registerable under its effective TLD.

The project compiles curated TLD rule data from rules/*.toml into the binary at build time. Rule coverage is bootstrapped from the ICANN section of the Public Suffix List, while concrete registration policy remains explicit and source-backed.

Highlights

• Rust core with PyO3 Python bindings.
• Build-time TOML validation and code generation.
• CLI for check, info, and stats.
• Checked-in ICANN PSL coverage plus grouped Spec 13 brand TLD rules.

Bootstrap Data

The repository already includes checked-in rule data under rules/*.toml.

That data includes:

• ICANN Public Suffix List coverage represented as minimal [[domains]] entries
• grouped ICANN Spec 13 brand TLD rules in rules/_brand.toml
• curated rule entries where registration policy is explicitly tracked and sourced
