PooledGuard

reifydb_core::value::column::pool::guard

Struct PooledGuard

pub struct PooledGuard<T: Releasable> { /* private fields */ }

Expand description

A guard that automatically returns a container to its pool when dropped

This implements the RAII pattern for container pooling - when the guard goes out of scope, it automatically releases the contained value back to the pool for reuse.
