CollectionQueryStatic

Struct CollectionQueryStatic 

Source
pub struct CollectionQueryStatic<'q, Root, Item>
where Root: 'static, Item: 'static,
{ /* private fields */ }
Expand description

Query builder for collection keypaths with 'static lifetime (e.g. from #[derive(Kp)]). Pass the root when calling execute, count, exists, or first.
