Struct PhpGetterMap 

pub struct PhpGetterMap {
    pub getters: HashMap<String, HashSet<String>>,
    pub field_types: HashMap<String, HashMap<String, String>>,
    pub root_type: Option<String>,
}

Per-type PHP getter classification + chain-resolution metadata.

Holds enough information to resolve a multi-segment field path through the IR’s nested type graph and pick the correct accessor style at each segment:

• getters[type_name] — set of field names on type_name whose PHP binding uses a #[php(getter)] method (caller must emit ->getCamelCase()).
• field_types[type_name][field_name] — the IR-resolved Named type that field_name traverses into, used to advance the “current type” cursor for the next path segment. Absent for terminal/scalar fields.
• root_type — the IR type name backing the result variable at the start of any chain. When None, chain traversal degrades to per-segment lookup using a flattened union across all types (legacy bare-name behaviour), which produces false positives when field names collide across types.

Fields

getters: HashMap<String, HashSet<String>>

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

root_type: Option<String>

Implementations

impl PhpGetterMap

pub fn needs_getter(&self, owner_type: Option<&str>, field_name: &str) -> bool

Returns true if (owner_type, field_name) requires getter-method syntax.

When owner_type is None (root type unknown, or chain advanced into an unmapped type), falls back to the union across all types: any type declaring field_name as non-scalar marks it as needing a getter. This is the legacy behaviour and is unsafe when field names collide.

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 is_empty(&self) -> bool

True when no per-type information is recorded — equivalent to the legacy “no PHP getter resolution” code path.
