Type Definition js::jsapi::BuildIdOp

type BuildIdOp = Option<unsafe extern "C" fn(buildId: *mut BuildIdCharVector) -> bool>;

Return the buildId (represented as a sequence of characters) associated with the currently-executing build. If the JS engine is embedded such that a single cache entry can be observed by different compiled versions of the JS engine, it is critical that the buildId shall change for each new build of the JS engine.
