Adds a new {Edge} to the dependency graph without checking for circularity. @param (see add_edge) @return (see add_edge)
@return [Boolean] where the requirement of the state we’re unwinding
to directly caused the conflict. Note: in this case, it is impossible for the state we're unwinding to to be a parent of any of the other conflicting requirements (or we would have circularity)
Filter’s a state’s possibilities to remove any that would not satisfy the requirements in the conflict we’ve just rewound from @param [UnwindDetails] unwind_details details of the conflict just unwound from @return [void]
Filter’s a state’s possibilities to remove any that would (eventually) create a requirement in the conflict we’ve just rewound from @param [UnwindDetails] unwind_details details of the conflict just unwound from @return [void]
Ensures any raised {NoSuchDependencyError} has its {NoSuchDependencyError#required_by} set. @yield
