regorus

Regorus is

  • Rego-Rus(t) - A fast, light-weight Rego interpreter written in Rust.
  • Rigorous - A rigorous enforcer of well-defined Rego semantics.

Regorus can be used in Python via regorus package. (It is not yet available in PyPI, but can be manually built.)

See Repository.

Automation

Run cargo xtask build-python to produce wheels via maturin, or cargo xtask test-python to reinstall the package locally and execute the sample script and pytest suite.

To build this binding, see building

Usage

import regorus

# Create engine
engine = regorus.Engine()

# Load policies
engine.add_policy_from_file('../../tests/aci/framework.rego')
engine.add_policy_from_file('../../tests/aci/api.rego')
engine.add_policy_from_file('../../tests/aci/policy.rego')

# Add policy data
