Type representing a file that will hold a series of heap snapshots together with additional information required to interpret those snapshots.

create ~path creates a series file at path.

save_event writes an event, which is an arbitrary string, into the given series file. This may be used for identifying particular points during program execution when analysing the profile. The optional time parameter is as for Snapshot.take.

save_and_close series writes information into series required for interpeting the snapshots that series contains and then closes the series file. This function must be called to produce a valid series file. The optional time parameter is as for Snapshot.take.
