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.

Return an integer describing the current format of stats, nodes, and edges

namespace HH;

function heapgraph_version(): int;

This will be incremented when things change substantially enough to require client detection
