Rust: Drop Trait

Running some code on cleanup.

When your variable is removed from scope, then the drop function is called on it. This is inserted by Rust.

Implementing the drop method yourself allows you to customize the cleanup code that needs to run when this instance goes out of scope.

You can use this implementation to release resources like files or network connections.

#rust #drop #cleanup

Should have shown how the drop function is implemented. Which is literally an empty block.

I would love if the Rust compiler called drop after last use, instead of when it exits scope. That's how I personally usually do it in C and C++ (when I manage by hand)
