Struct EuvDebugProps 

pub struct EuvDebugProps {
    pub label: &'static str,
    pub value: Option<DebugValueFormatter>,
    pub expanded: bool,
}

Props for the euv_debug component.

Defines the strongly-typed interface for the dev-only Debug readout. The component renders a labeled <pre data-euv-debug> block whose body is the result of invoking value on every render, so users can inspect reactive state without breaking out of the component tree.

value is wrapped in Option<DebugValueFormatter> (rather than DebugValueFormatter directly) so the struct can derive Default — the upstream #[derive(New)] macro expects every props struct to also be Default (it generates X::new(...) AND X::default() from the same field list). A bare Rc<dyn Fn() -> String> has no Default impl (you cannot synthesise an arbitrary formatter), so wrapping in Option keeps the derive happy and gives us a sensible “no formatter configured” fallback.

Fields

label: &'static str

Short label printed before the value (e.g. “count”, “user”). Rendered as <span data-euv-debug-label>{label}</span> so styling hooks ([data-euv-debug-label]) can target it independently from the value.

value: Option<DebugValueFormatter>

Optional closure that produces the displayable string. Runs on every render — typically the body reads one or more Signal<T>::get() values to subscribe the readout to live state. None renders an empty placeholder so the caller can still construct the component without a formatter (handy in tests and stub components).

expanded: bool

When true, the value is rendered inside <pre> with white-space: pre-wrap so multi-line strings (JSON, stack traces) preserve formatting. When false, the value is rendered inside a single-line <code>.
