ext_factparse_version

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 should be bumped with every non-backwards compatible API change 1 => first version 2 => added $root argument to HH\facts_parse() 3 => support requireExtends/requireImplements constraints

namespace HH;

function ext_factparse_version(): int;
