Douglas Creager c60e590b4c [ty] Support variable-length tuples in unpacking assignments (#18948) ... This PR updates our unpacking assignment logic to use the new tuple machinery. As a result, we can now unpack variable-length tuples correctly. As part of this, the `TupleSpec` classes have been renamed to `Tuple`, and can now contain any element (Rust) type, not just `Type<'db>`. The unpacker uses a tuple of `UnionBuilder`s to maintain the types that will be assigned to each target, as we iterate through potentially many union elements on the rhs. We also add a new consuming iterator for tuples, and update the `all_elements` methods to wrap the result in an enum (similar to `itertools::Position`) letting you know which part of the tuple each element appears in. I also added a new `UnionBuilder::try_build`, which lets you specify a different fallback type if the union contains no elements.		2025-06-27 15:29:04 -04:00
