Struct InvalidTransitiveDependency

pub struct InvalidTransitiveDependency(/* private fields */);

An error that can be returned during “world elaboration” during various Resolve operations.

Methods on Resolve which mutate its internals, such as Resolve::push_dir or Resolve::importize can fail if world imports in WIT packages are invalid. This error indicates one of these situations where an invalid dependency graph between imports and exports are detected.

Note that at this time this error is subtle and not easy to understand, and work needs to be done to explain this better and additionally provide a better error message. For now though this type enables callers to test for the exact kind of error emitted.
