Struct TableReadGuard 

Source 
pub struct TableReadGuard<'a, K, V, S = RandomState> { /* private fields */ }
Expand description

A RAII guard, that provides read access to the Table entry’s value.

Created by the Table::get or Table::try_get methods.

The guard keeps the corresponding Table shard locked for read until the guard is dropped.
