The RAII Drop-Guard Pattern in Rust

The RAII Drop-Guard Pattern in Rust Context In Rust, any value that owns a resource and frees it in its Drop implementation acts as a guard : the resource lives for exactly as long as the value is in scope. This is RAII - Resource Acquisition Is Initialization - and in Rust it is the primary, statically-enforced mechanism for resource management.
