Failure to build 1.4.0 on existing projects that were using 1.3.2 #203
Description
It seems that 1.4.0 is making assumptions about items in the current space, which is a breaking change, and fails to build on projects who were dependent on any 1 version, such as previously 1.3.2.
I discovered this error because projects using new projects created using the soroban-sdk crate started pulling in arbitrary and derive_arbitrary 1.4.0 and see build errors.
$ git clone https://github.com/stellar/rs-soroban-sdk
$ git checkout fc32690edd223fd01054c625d9c6dca01bd99e67 # main at today's date
$ cd rs-soroban-sdk
$ cargo update arbitrary --precise 1.4.0
$ cargo test
Included in the output are the following build errors:
