strval() — internals
Where it lives
- Signature:
src/builtins/types/strval.rs - Lowering:
src/builtins/semantics.rs:639 (lower_registry_call) - Function symbol:
lower_registry_call()
Lowering notes
- Uses the
eir_primitivestrategy from the single-source builtin descriptor. - Emits backend-neutral EIR primitives or a small EIR graph through
BuiltinLoweringContext.
Semantic descriptor
- Target strategy:
eir_primitive - Validation:

EIR and runtime boundary
- Typed EIR target: descriptor-emitted EIR primitives or graph; no opaque builtin call remains.
