Struct PackageSet 

pub struct PackageSet { /* private fields */ }

A set of packages with a complete dependency closure.

Implementations

impl PackageSet

pub fn load<P: AsRef<Path>>( paths: impl IntoIterator<Item = P>, ) -> Result<Self, LoadError>

Reads every package at paths (.tgz files or unpacked directories) and builds the set.

Errors

Returns LoadError when a package cannot be read, or as PackageSet::new does.

pub fn new(packages: Vec<Package>) -> Result<Self, LoadError>

Builds the set from packages already read, checking the closure.

Every dependency a manifest names SHALL be listed, and a version whose patch is x accepts the highest patch present (https://hl7.org/fhir/packages.html, §2.1.10.2).

Errors

Returns LoadError::DuplicatePackage for a name and version given twice, and LoadError::MissingDependency naming the first dependency the set does not hold.

pub fn packages(&self) -> &[Package]

Returns the packages of the set, sorted by name and version.

pub fn structure_definition( &self, canonical: &str, ) -> Result<Arc<StructureDefinition>, ResolveError>

Resolves canonical to the StructureDefinition it names.

url|version resolves to that version. A bare url resolves to its one version, or to the latest when the set carries several, as R4 asks (https://hl7.org/fhir/R4/references.html#canonical, §2.3.0.5); the order is compare_versions, and a definition without a version sorts below every versioned one.

Errors

Returns ResolveError when nothing matches, the canonical names a contained resource, two different definitions share the URL and version, or the definition does not decode.

pub fn value_set(&self, canonical: &str) -> Result<Arc<ValueSet>, ResolveError>

Resolves canonical to the ValueSet it names, by the rules of PackageSet::structure_definition.

Errors

Returns ResolveError as PackageSet::structure_definition does.

pub fn code_system( &self, canonical: &str, ) -> Result<Arc<CodeSystem>, ResolveError>

Resolves canonical to the CodeSystem it names, by the rules of PackageSet::structure_definition.

Errors

Returns ResolveError as PackageSet::structure_definition does.
