Struct Schemas

Source

pub struct Schemas {
    pub types: &'static [TypeSchema],
    pub resources: &'static [&'static str],
    pub primitives: &'static [PrimitiveSchema],
}

Expand description

A version’s schema: every type, sorted by name, the resource names and the primitive types.

Fields§

§types: &'static [TypeSchema]

The types, sorted by name.

§resources: &'static [&'static str]

The resource type names, sorted.

§primitives: &'static [PrimitiveSchema]

The primitive types, sorted by name.

Implementations§

Source §

impl Schemas

Source

pub fn type_named(&self, name: &str) -> Option<&'static TypeSchema>

The schema of the type named name.

Source

pub fn base_of(&self, name: &str) -> Option<&'static str>

The name of the type name specializes, None for a type at the root of the hierarchy and for a name the table does not carry.

Source

pub fn primitive_base_of(&self, name: &str) -> Option<&'static str>

The type the primitive name specializes, None for a code that names no primitive and for a primitive whose definition names no base.

Source

pub fn specializes(&self, name: &str, ancestor: &str) -> bool

Whether the type name is ancestor or specializes it, directly or through its base chain: Age specializes Quantity, and Patient specializes DomainResource and Resource (https://hl7.org/fhir/R5/types.html).

Source

pub fn element( &self, path: &str, ) -> Option<(&'static TypeSchema, &'static FieldSchema)>

The type and element a dotted element path names.

The walk starts at the resource or datatype the first segment names and follows each further segment through the complex and backbone types the elements hold, including the hop a contentReference makes (https://hl7.org/fhir/R4/elementdefinition.html). A choice element answers to its base path (Observation.value[x]) and to every expanded form the JSON representation gives it (Observation.valueQuantity, https://hl7.org/fhir/R4/json.html). A path that continues through a primitive, through a resource-typed element, or through the base form of a choice has no element here, and neither has a path the schema does not know.

Source

pub fn type_of(&self, path: &str) -> Option<&'static TypeSchema>

The type an element path resolves to.

A bare type name resolves to that type; an element path resolves to the complex or backbone type the element holds. A primitive element has no type here, because the schema carries only complex types.
