[INFO] [stdout] warning: use of deprecated macro `serde::serde_if_integer128`: 
[INFO] [stdout]          This macro has no effect on any version of Serde released in the past 2 years.
[INFO] [stdout]          It was used long ago in crates that needed to support Rustc older than 1.26.0,
[INFO] [stdout]          or Emscripten targets older than 1.40.0, which did not yet have 128-bit integer
[INFO] [stdout]          support. These days Serde requires a Rust compiler newer than that so 128-bit
[INFO] [stdout]          integers are always supported.
