Struct WeakRocksDB

Source 
pub struct WeakRocksDB<CF> { /* private fields */ }
Expand description

Weak reference to a RocksDB instance. Doesn’t prevent dropping the underlying instance; to work with it, you should upgrade the reference first.

The wrapper is cheaply cloneable; internally, it wraps a DB instance in a Weak.

Implementations§

Source§

impl<CF: NamedColumnFamily> WeakRocksDB<CF>

Source

pub fn upgrade(&self) -> Option<RocksDB<CF>>
