Struct WidgetDataFn 

pub struct WidgetDataFn(/* private fields */);

Wrapper around the async data closure. Build via WidgetDataFn::new (closure ignores per-request params) or WidgetDataFn::with_params (closure reads WidgetParams to honour period / date-range filters from the request URL).

Implementations

impl WidgetDataFn

pub fn new<F, Fut>(f: F) -> Self

where F: Fn(AuthUser) -> Fut + Send + Sync + 'static, Fut: Future<Output = WidgetPayload> + Send + 'static,

Create from any async fn(AuthUser) -> WidgetPayload — per-request params are dropped on the floor. Use when the widget renders the same thing regardless of UI controls (KPI counts, registry sizes, etc.).

pub fn with_params<F, Fut>(f: F) -> Self

where F: Fn(AuthUser, WidgetParams) -> Fut + Send + Sync + 'static, Fut: Future<Output = WidgetPayload> + Send + 'static,

Create from async fn(AuthUser, WidgetParams) -> WidgetPayload. Use for filterable widgets — the line chart reads params.period to switch between 7d / 30d / 90d views, a future table widget might read params.raw.get("status") for status filtering, etc.
