Released a TOML library with zero dependencies in Rust.

Source: Dev.to

Overview

Shiguredo is shifting its development focus from C++ to Rust. As part of this transition, we have implemented various libraries in Rust, and we are now releasing a TOML library.

Features

• Zero dependencies – the library has no external dependencies.
• Specification support – compatible with TOML v1.0.0 and v1.1.0.
• Full test suite compatibility – passes the official toml-test suite with a 100 % score, indicating full compatibility.
• Fuzzing support – extensive fuzz testing ensures robustness against unexpected inputs.
• Rewriting functionality – added based on user requests, using the positional‑tracking mechanism from the nojson library.

Implementation Details

• The library builds on Shiguredo’s internal approach of minimizing dependencies by creating and maintaining our own Rust libraries.
• Rewriting capabilities were introduced after fixing several identified bugs, leveraging the positional tracking used in the dependency‑free nojson JSON library.
