Struct Engine 

pub struct Engine<'a, X> { /* private fields */ }

Runs StructureMaps.

Implementations

impl<'a, X: Expressions> Engine<'a, X>

pub fn new(definitions: &'a dyn Definitions, expressions: X) -> Self

pub fn with_trace(self, trace: bool) -> Self

Records a debug trace of each transform: see Trace.

pub fn with_concept_maps(self, concept_maps: &'a dyn ConceptMapResolver) -> Self

Where translate finds ConceptMaps that are not contained in the map.

pub fn with_translator(self, translator: &'a dyn TranslateService) -> Self

A terminology service for translate with ConceptMaps neither the map nor the resolver holds.

pub fn with_limits(self, limits: Limits) -> Self

How much a transform may do; see Limits.

pub fn with_cancellation(self, cancel: &'a AtomicBool) -> Self

A flag the caller sets to stop running transforms; they fail with ErrorKind::Cancelled at the next rule.

pub fn with_ids(self, ids: &'a dyn IdGenerator) -> Self

Where uuid() and new resource ids come from; random by default.

pub fn with_maps(self, maps: &'a dyn MapResolver) -> Self

Where the maps named in imports come from.

pub async fn transform( &self, map: &StructureMap, source: &Value, ) -> Result<Transformed, Error>

Transforms source with the map’s first group; the target is created from the type of that group’s target parameter.

pub async fn transform_into( &self, map: &StructureMap, source: &Value, target: &Value, ) -> Result<Transformed, Error>

Transforms source into an existing target.
