Struct DynamicQuery 

pub struct DynamicQuery { /* private fields */ }

Runtime-defined questions with runtime-keyed answers. Choose this explicitly when the application cannot know the question set at compile time.

Implementations

impl DynamicQuery

pub fn new( definitions: BTreeMap<String, Question>, ) -> Result<Self, ProviderError>

Validate runtime question definitions before accepting them.

Trait Implementations

impl Clone for DynamicQuery

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DynamicQuery

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

Formats the value using the given formatter.

impl Query for DynamicQuery

type Output = BTreeMap<String, Answer>

The validated application answer shape.

type Response = BTreeMap<String, Answer>

The intermediate response shape deserialized by Serde.

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 Serialize for DynamicQuery

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
