Struct SstFileManager 

pub struct SstFileManager(/* private fields */);

SstFileManager is used to track SST files in the database and control their deletion rate.

All SstFileManager public functions are thread-safe.

SstFileManager can be used to:

• Set a limit on the total size of SST files. Once the limit is exceeded, writes will fail with a specific status.
• Control the deletion rate of obsolete files to avoid saturating the disk bandwidth with deletion operations.
• Track the total size of SST files and the total size of trash files.
