QUESTION
After figuring out cargo build of the same code: spurious compile time errors?, I want to know how to prevent such a problem:
...ANSWER
Answered 2017-Jul-25 at 19:44It is known issue, related links:
the short summary:
crate's features are supposed to be additive
In other words each feature in crate should only append functionality,
not change API. Unfortunately there no good documentation descrbing this problem,
and no automation for testing of this invariant at least at this moment.
This particular issue is related to nom
bug (github issue),
quote from there:
The problem here is that, when using "simple errors", the type
nom::simple_errors::Err
is simply a type alias ofnom::ErrorKind
, while with "verbose errors" the typenom::verbose_errors::Err
is a dedicated enum, so the "with-feature" and "without-feature" interfaces are incompatible.
