Owen Nelson commented on ARROW-4189:
------------------------------------
[~csun] I'd expect to see output like this when using an older version of the
rust toolchain (lower than 1.31). Support for editions was added to cargo with
1.31, along with _almost but not all_ of the module system updated (there were
some minor changes made in the subsequent 1.32 release).
Do you happen to know which version of the toolchain you saw this with?
