Common Rust Errors & Quick Fixes
Cause: Violating Rust aliasing rules by holding an immutable reference while attempting a mutable borrow.
Fix: Limit the lifetime of the immutable borrow or restructure the mutation to happen after reading.
Cause: Attempting to take ownership of a non-Copy value through a borrowed reference.
Fix: Use .clone() or borrow the value instead of moving ownership.
Cause: Omitting a semicolon at the end of a statement that is not the function return expression.
Fix: Add a semicolon ; to complete the statement.
