Function prompt_rollback 

pub fn prompt_rollback(backup: &[u8], path: &Path) -> Result<()>

Prompt user for action when validation fails: retry, rollback, or abort.

Displays the validation error and presents an interactive prompt with three options:

• ‘y’ or ‘retry’: Re-open the editor for another attempt (returns Ok)
• ‘r’ or ‘rollback’: Restore the original file from backup and abort (returns Ok)
• ‘n’ or any other input: Abort the edit operation (returns Err)

Arguments

• backup - The original file content before editing (in bytes)
• path - Path to the bean file being edited

Returns

• Ok(()) if user chooses ‘retry’ (signals caller to re-open editor) or ‘rollback’
• Err if user chooses ‘n’/‘abort’

Examples

match prompt_rollback(&backup, &path) {
    Ok(()) => {
        // User chose retry or rollback - check backup file to determine which
        if path matches backup { /* was rollback */ }
        else { /* was retry */ }
    }
    Err(e) => println!("Edit aborted: {}", e),
}
