NoDoc
Note
This is a point-in-time snapshot of the API documentation from January 2026. Going forward, we will not be maintaining a public copy of these references, and recommend users to refer to the built-in signature helpers available in the Hack LSP instead for complete and up-to-date information.
This attribute is used by documentation generation for docs
hhvm.com to hide annotated functions from having documentation generated for them. This is generally because said functions are implementation details of some kind.
