Overview

Package bundle implements bundle loading.

Deprecated: This package is intended for older projects transitioning from OPA v0.x and will remain for the lifetime of OPA v1.x, but its use is not recommended. For newer features and behaviours, such as defaulting to the Rego v1 syntax, use the corresponding components in the github.com/open-policy-agent/opa/v1 package instead. See https://www.openpolicyagent.org/docs/latest/v0-compatibility/ for more information.

If the Rego file already had an overriding rego version, it will be preserved. If a single bundle is provided, it will retain any rego version information it already had. If it has none, the provided regoVersion will be applied to it. If usePath is true, per-file rego-versions will be calculated using the file's ModuleFile.Path; otherwise, the file's ModuleFile.URL will be used.
