Failed to find package {package}

Error message

Failed to find package {package}

What it means

Failure of Workspace::find_main_package after exhaustive search of workspace members: the requested package name is not a member of the current cargo workspace. Diagnostic errors listing all workspace members are logged first; the faulting input is the package name from CLI/config that must be added to the workspace.
