provides_unique

This field contains an optional list of virtual module names that this context uniquely provides.

Like provides, but also adds the listed names to conflicts. This means only one context (or module) that provides the same name via provides_unique can be active in a build.

Example:

contexts:
  - name: context_uart
    parent: default
    provides_unique:
      - serial_backend

  - name: context_usb
    parent: default
    provides_unique:
      - serial_backend

In this example, a build cannot use both context_uart and context_usb since they both uniquely provide serial_backend.
