This directory contains the renderer-specific portions of the Feature Policy API.
This includes:
The parser for the HTTP Feature-Policy header and the iframe allow attribute.
Helpers for manipulating the parsed declarations.
Implementation of the document.policy and iframe.policy interfaces.
The core feature policy algorithms can be found in /common/feature\_policy/.
The feature list enum is found in /public/mojom/feature\_policy/.
The recommended API for checking whether features should be enabled or not is Document::IsFeatureEnabled() (or SecurityContext::IsFeatureEnabled in a non- document context).
