use thiserror::Error;

/// Error type for display operations in `JouleProfiler`.
///
/// This enum represents errors that can occur when displaying or exporting
/// profiler results, whether to the terminal, JSON, or CSV.
///
/// # Variants
///
/// - `NotImplementedForFormat`: The requested display format does not support
///   the attempted operation (e.g., trying to list sensors in CSV output).
///
/// - `IoError` ([`std::io::Error`]): I/O error occurred during display,
///   e.g., writing to a file failed.
///
/// - `SerializeError` ([`serde_json::Error`]): Serialization error occurred
///   when exporting to JSON format.
