Struct Nested 

pub struct Nested<E = Root, C = Value> { /* private fields */ }

A nested array of objects. E is the enclosing scope (where queries over this array land — Root at the top level, the parent element type when deeper); C is the child scope (the element type). Lifting a child query (Query<C>) through any/all produces a Query<E>.

Implementations

impl<E, C> Nested<E, C>

pub fn at(path: impl Into<String>) -> Self

pub fn any(&self, query: impl AsQuery<C>) -> Query<E>

Parents with at least one element matching query.

pub fn all(&self, query: impl AsQuery<C>) -> Query<E>

Parents where every element matches query (“no element fails it”).

pub fn exists(&self) -> Query<E>

The nested array has at least one element.

pub fn matching(&self, query: impl AsQuery<C>) -> NestedProjection

Shape the returned array: keep elements matching query (with the builder’s sort/size). Pass to crate::Search::filter_nested.

pub fn project(&self) -> NestedProjection

Like matching with no predicate — every element.

Trait Implementations
