3This macro has no effect on any version of Serde released in the past 2 years.
4It was used long ago in crates that needed to support Rustc older than 1.26.0,
5or Emscripten targets older than 1.40.0, which did not yet have 128-bit integer
6support. These days Serde requires a Rust compiler newer than that so 128-bit
7integers are always supported.
