Struct FieldGenerator 

pub struct FieldGenerator<'a> { /* private fields */ }

Generator for creating Rust fields from FHIR ElementDefinitions

Implementations

impl<'a> FieldGenerator<'a>

pub fn new( config: &'a CodegenConfig, type_cache: &'a HashMap<String, RustStruct>, value_set_manager: &'a mut ValueSetManager, ) -> Self

Create a new field generator

pub fn create_fields_from_element( &mut self, element: &ElementDefinition, ) -> CodegenResult<Vec<RustField>>

Create RustField(s) from an ElementDefinition Returns a vector because choice types generate multiple fields

pub fn create_field_from_element( &mut self, element: &ElementDefinition, ) -> CodegenResult<Option<RustField>>

Legacy method for backward compatibility

pub fn to_rust_field_name(name: &str) -> String

Convert a FHIR field name to a valid Rust field name

pub fn type_code_to_snake_case(type_code: &str) -> String

Convert FHIR type code to snake_case for field suffix

pub fn extract_field_name_from_path(path: &str) -> &str

Extract field name from element path (utility method)

pub fn requires_serde_rename(original_name: &str, rust_field_name: &str) -> bool

Check if a field name requires serde rename

pub fn determine_field_cardinality(element: &ElementDefinition) -> (bool, bool)

Determine field cardinality from ElementDefinition

pub fn extract_choice_types_from_structure( structure_def: &StructureDefinition, ) -> Vec<(String, Vec<String>)>

Extract choice type information from a StructureDefinition Returns a vector of (base_name, type_codes) tuples for each choice type found

pub fn create_primitive_field_macro_call( &mut self, element: &ElementDefinition, ) -> CodegenResult<Option<RustField>>

Generate explicit primitive fields with companion extension fields This creates two RustField instances: the primitive field and its companion Element field

pub fn create_companion_extension_field( &self, field_name: &str, ) -> CodegenResult<RustField>

Generate the companion extension field for a primitive field Returns a RustField representing the _fieldname extension companion
