The Drop Trait

The Drop trait in Rust is used to run custom cleanup logic when a value goes out of scope. This is particularly useful for managing resources like files, network connections, or any other system resources that need to be explicitly released.

When a value that implements Drop goes out of scope, the Rust runtime automatically calls the drop method, allowing you to define custom behavior for resource cleanup.

In this challenge, you will implement a struct that represents a temporary file. The file should be automatically deleted when the struct is dropped, simulating the behavior of temporary files in real-world applications.

Your Task

Create TempFile struct with a method new that takes a file name as input, it must accept both &str and String types.
Implement the Drop trait for TempFile to delete the file automatically when the struct goes out of scope.

Hints

If you're stuck, here are some hints to help you solve the challenge:

Click here to reveal hints

Use std::fs::File to create a temporary file.
Use std::env::temp_dir() to get the path for temporary files.
The std::fs::remove_file method can be used to delete files.
The PathBuf struct is helpful for managing file paths.
Use the AsRef<str> trait to allow flexible input types for the file name.
Implement the Drop trait for custom cleanup logic.
