    /// “Completion functionality” means that when the user modifies the text
    /// in the entry, [`EntryCompletion`][crate::EntryCompletion] checks which rows in the model match
    /// the current content of the entry, and displays a list of matches.
    /// By default, the matching is done by comparing the entry text

    /// [`set_text_column()`][Self::set_text_column()]), but this can be overridden
    /// with a custom match function (see [`set_match_func()`][Self::set_match_func()]).
    ///
    /// When the user selects a completion, the content of the entry is
    /// updated. By default, the content of the entry is replaced by the
    /// text column of the model, but this can be overridden by connecting
    /// to the `signal::EntryCompletion::match-selected` signal and updating the
