Returns the status of all threads that belong to the current Env.

Get thread pool queue length for specific thread pool.

Returns the pointer to ThreadStatusUpdater. This function will be used in RocksDB internally to update thread status and supports GetThreadList().

Stream subset

Hash 128 input bits down to 64 bits of output. This is intended to be a reasonably good hash function.

This probably works well for 16-byte strings as well, but it may be overkill in that case.

Return an 8-byte hash for 33 to 64 bytes.

Restore the capacity reduced by a prior call to Deflate().

Returns true iff the status indicates an IOError.
