Struct NamedQuery 

pub struct NamedQuery<Q> { /* private fields */ }

A standalone question serialized under a runtime ID.

Trait Implementations

impl<Q: Clone> Clone for NamedQuery<Q>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<Q: Debug> Debug for NamedQuery<Q>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<Q: Query> Query for NamedQuery<Q>

type Response = BTreeMap<String, <Q as Query>::Response>

The intermediate response shape deserialized by Serde.

type Output = <Q as Query>::Output

The validated application answer shape.

fn decode( &self, response: Self::Response, ) -> Result<Self::Output, ProviderError>

Validate and convert a deserialized response. Composite queries delegate to their fields, keeping validation inside the evaluation error boundary.

fn named(self, id: impl Into<String>) -> Result<NamedQuery<Self>, ProviderError>

where Self: Sized,

Give a standalone question a runtime ID. Named struct fields do not need this.

fn join<Q: Query>(self, other: Q) -> JoinedQuery<Self, Q>

where Self: Sized,

Flatten two object-shaped queries into one evaluation request. Duplicate IDs are rejected before sending the request. Child queries must serialize with stable field names: decoding uses those names to partition the response before delegating to each child.

fn map<A, F>(self, map: F) -> MappedQuery<Self, F>

where Self: Sized, F: Fn(Self::Output) -> A + WasmCompatSend + WasmCompatSync,

Project validated answers into an application value.

impl<Q: Serialize> Serialize for NamedQuery<Q>

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
