hedron-native

Optional Rust acceleration for Hedron bulk HTML escaping.

Pure Python remains the semantic reference and Supported fallback. Absence of the extension never changes public rendering semantics — hedron-core uses these helpers when the package is installed and falls back otherwise.

Also available as the flagship extra hedron[native].

Package maturity: Beta (0.1.x) · pin >=0.1.1,<0.2 and expect churn

Install

pip install "hedron-native>=0.1.1,<0.2"
# or
uv add "hedron-native>=0.1.1,<0.2"
# via flagship:
pip install "hedron[native]>=0.28.0,<0.29"

Requires Python 3.11–3.14. Prebuilt wheels are published for common platforms; if a wheel is unavailable, pip may build from the Rust source (requires a Rust toolchain) or you can rely on the pure-Python path without this package.

Quick start

from hedron_native import (
    escape_attr,
    escape_attr_python,
    escape_text,
    escape_text_python,
    native_available,
)

assert escape_text("<x>") == "&lt;x&gt;"
assert escape_attr('"') == "&quot;"

# Always available, even when the extension did not load:
assert escape_text_python("<x>") == "&lt;x&gt;"
assert escape_attr_python('"') == "&quot;"

print("native extension loaded:", native_available())
