Struct DartFirstClassMap 

pub struct DartFirstClassMap {
    pub field_types: HashMap<String, HashMap<String, String>>,
    pub root_type: Option<String>,
    pub stringy_fields_by_type: HashMap<String, Vec<StringyField>>,
}

Dart opaque type classification + chain-resolution metadata, mirroring Swift’s needs to track stringy field accessors on element types for Vec<T> contains assertions. Unlike Swift, Dart doesn’t distinguish first-class vs opaque; we just track stringy fields per type.

Fields

field_types: HashMap<String, HashMap<String, String>>

root_type: Option<String>

stringy_fields_by_type: HashMap<String, Vec<StringyField>>

Per-type readable text accessors. Used by the dart e2e contains assertion to aggregate every stringy field on a Vec<T> element type.

Implementations

impl DartFirstClassMap

pub fn advance( &self, owner_type: Option<&str>, field_name: &str, ) -> Option<String>

Returns the IR Named type that field_name traverses into for the next chain segment, or None if the field is terminal/scalar/unknown.

pub fn stringy_fields(&self, type_name: &str) -> Option<&[StringyField]>

Returns the list of stringy accessors recorded for type_name, or None if the type has no recorded stringy fields.

pub fn is_empty(&self) -> bool

True when no per-type information is recorded.

Trait Implementations

impl Clone for DartFirstClassMap

fn clone(&self) -> DartFirstClassMap

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DartFirstClassMap

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DartFirstClassMap

fn default() -> DartFirstClassMap

Returns the “default value” for a type.
