Module typed_result 

Typed Result representations for v2 runtime.

Result<T, E> is a tagged union: tag (0=Ok, 1=Err) + payload. Size = 8 + max(sizeof(T), sizeof(E)). Monomorphized per instantiation.

Since Rust #[repr(C)] unions with generics are awkward, we provide concrete instantiations for common Shape result types.

Structs

ResultF64Str

Result<f64, *const StringObj> — Ok is f64, Err is string pointer.

ResultI64Str

Result<i64, *const StringObj> — Ok is i64, Err is string pointer.

ResultPtrStr

Result<*const T, *const StringObj> — Ok is a heap pointer, Err is string pointer.

Constants

RESULT_OFFSET_PAYLOAD

RESULT_OFFSET_TAG

Byte offset constants for JIT codegen.

RESULT_TAG_ERR

Tag value for Err variant.

RESULT_TAG_OK

Tag value for Ok variant.
