Is it possible to parse into an already boxed struct?

[alexeysofin]

When parsing a large object, and then boxing it, rust will allocated the struct on stack and then copy it's contents to heap, with huge objects that can be problematic performance-wise, are there any solutions to this?

There is https://docs.rs/serde/latest/src/serde/de/mod.rs.html#572 which should allow you to do that, but you do need an already initialized object, and your data structures need to support this as the default just allocates on the stack first and moves the value over afterwards.

great, thank you!
