{self:?} is not a named SearchOption

Error message

{self:?} is not a named SearchOption

What it means

SearchOption::icon() maps only the four options rendered as toolbar toggle buttons (WholeWord, CaseSensitive, IncludeIgnored, Regex) to icons; every other variant falls into the wildcard panic arm (crates/search/src/search.rs:115). It is a tripwire forcing new SearchOption variants to be classified: either a named toolbar button or something that must never be rendered as one.

Solutions

1. Only pass the four toggle-capable options down icon/button paths; keep an explicit const list (WholeWord, CaseSensitive, IncludeIgnored, Regex) for the toolbar.
2. If the new variant should be a toolbar button, add it to icon(), the label/action mapping, and to_toggle_action() in the same change.
3. Replace the wildcard arm with an exhaustive match so unclassified variants become compile errors instead of runtime panics.
4. Use the backtrace to find the caller (usually as_button via the search toolbar construction) and what variant it passed.

Example fix

// before
match self {
    SearchOption::WholeWord => IconName::WholeWord,
    _ => panic!("{self:?} is not a named SearchOption"),
}

// after: exhaustive match forces classification of new variants
match self {
    SearchOption::WholeWord => IconName::WholeWord,
    SearchOption::CaseSensitive => IconName::CaseSensitive,
    SearchOption::IncludeIgnored => IconName::FileIgnored,
    SearchOption::Regex => IconName::Regex,
    SearchOption::OneMatchPerLine | SearchOption::Backwards => {
        IconName::CaseSensitive // placeholder: decide deliberately
    }
}

fn is_toggle_button_option(option: SearchOption) -> bool {
    matches!(
        option,
        SearchOption::WholeWord
            | SearchOption::CaseSensitive
            | SearchOption::IncludeIgnored
            | SearchOption::Regex
    )
}

if is_toggle_button_option(option) {
    toolbar.child(option.as_button(active, source, focus_handle));
}

When it happens

Trigger: Calling SearchOption::icon() — directly or via as_button(), which builds the toolbar toggle — on SearchOption::OneMatchPerLine or SearchOption::Backwards. Typical shape: a loop over a list of 'all' options that renders each as a button.

Common situations: Making the search toolbar option list data-driven and feeding it every variant; adding a new SearchOption variant meant to be config-only but passed to the button builder; refactors that generalize option rendering.
