Struct PoolGuard

Source 
pub struct PoolGuard<T: PoolEntry> { /* private fields */ }
Expand description

A wrapper around an occupied entry of a Pool.

When this structure is dropped (falls out of scope) and the entry is not yet closed (is_closed), the entry will be reinserted into the pool.

The data protected by the mutex can be accessed through this guard via its Deref and DerefMut implementations.

This structure is created by the acquire method on Pool.
