/// # Examples
///
/// ```rust
/// use qubit_fs::copy::CopyFailureState;
///
/// assert_eq!(CopyFailureState::Unchanged, CopyFailureState::Unchanged);
/// ```
#[derive(Clone, Copy, Debug, Eq, PartialEq)]

    /// No destination effect was published.
    Unchanged,
    /// Some destination effects were published.
    PartiallyPublished,
    /// The destination was published before a later failure.
    Published,
    /// The provider cannot determine publication state.
    Indeterminate,
