This folder demonstrates handling recoverable errors in Rust, especially with file operations.

Topics Covered

• Using Result and match for error handling
• Handling file open and creation errors
• Matching on error kinds (e.g., NotFound)

Key Concepts

• Result<T, E>: Used for recoverable errors, allows handling different error cases
• ErrorKind: Enum for different types of I/O errors
• Graceful error handling and file creation

Example Highlights

• Attempt to open a file, create if not found
• Match on error kind to handle specific cases
• Panic only for truly unrecoverable errors

Error Chances

• File not found or cannot be created
• Other I/O errors

Usage

cargo run
cargo check

See src/main.rs for code examples and comments explaining each concept.
