void SnapshotPersistence (const std::optional<Root> & temp_root, const std::optional<Root> & persistent_root)Defined at line 74 of file ../../src/developer/forensics/crash_reports/snapshot_persistence.cc
std::optional<ItemLocation> Add (const std::string & uuid, const ManagedSnapshot::Archive & archive, StorageSize archive_size, bool only_consider_tmp)Adds a snapshot to persistence. If |only_consider_tmp| is true, only /tmp will be
considered as a possible storage location. Returns the location of the stored snapshot, if it
was stored.
Defined at line 99 of file ../../src/developer/forensics/crash_reports/snapshot_persistence.cc
bool Contains (const std::string & uuid)Returns true if a snapshot for |uuid| exists on disk.

void MoveToTmp (const std::string & uuid)Attempts to move the snapshot from /cache to /tmp. Will attempt to delete the snapshot from
/cache regardless of whether the addition to /tmp succeeds. Check-fails that the snapshot was
previously in /cache.
