⚡ oryaml

The fastest YAML parser for Python, written in Rust.

⚠️ Status: UNDER ACTIVE DEVELOPMENT > This library is currently in Pre-Alpha.
Do not use in production environments until the v0.1.0 release.

🚀 The Goal

oryaml aims to be for YAML what orjson is for JSON: a drop-in replacement that exploits Rust's zero-cost abstractions to achieve blazing-fast parsing speeds.

📊 Early Benchmarks

Even in this early prototype stage, oryaml is significantly faster than the standard PyYAML library.

Library	Parsing Time (50k records)	Speedup
PyYAML (CLoader)	~117.32s	1x
ruamel.yaml	~156.84s	0.7x
oryaml (v0.0.1)	~12.00s	~9.7x 🚀

(Benchmarks run on a ~106MB complex YAML file with deep nesting)

Performance Targets: Internal tests show potential for further significant reductions in parsing time as the engine matures. We are targeting a sub-4-second parse time for this dataset in the v0.1.0 release.

📦 Installation

Coming soon to PyPI.
