## Asserts the two `declareLibrary`/`genBindings` contracts that hold at macro
|
|
## time: the `ABIFormat` enum overload compiles, and an {.ffiCtor.} with no
|
|
## {.ffiDtor.} fails the build. Each fixture compiles in a child `nim check` so
|
|
## its expected result is an assertion rather than this file's own compile error.
