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_template_versions(self, versions: bool) -> Self

Whether a value carries a template only with the template’s version (templateId extension), as a profile’s identifier states it — the default — or with any version of it (the same root). Converters that must recognise documents written against earlier versions of the templates turn versions off.

pub fn with_lenient_translations(self, lenient: bool) -> Self

What translate does with a code whose ConceptMap element has no usable target (R4 unmatched or disjoint, R5 not-related-to, or several): fail the transform, as the reference engine does (the default), or leave the target unset and report a warning, as for a code the ConceptMap does not list. Converters of whole documents leave it out.

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.
