// Some pod and container fields are restricted if this is set.
  //
  // If the OS field is set to linux, the following fields must be unset:
  // -securityContext.windowsOptions
  //
  // If the OS field is set to windows, following fields must be unset:
  // - spec.hostPID
  // - spec.hostIPC
  // - spec.hostUsers
  // - spec.securityContext.seLinuxOptions
  // - spec.securityContext.seccompProfile

* Mark image as deliberately optional in v1 Container struct.  Many objects in the Kubernetes API inherit the container struct and only Pods require the field to be set. ([#48406](https://github.com/kubernetes/kubernetes/pull/48406), [@gyliu513](https://github.com/gyliu513))

From (1) a compiler can infer that the type argument for <code>S</code> is <code>Slice</code>.
Similarly, because the underlying type of <code>Slice</code> is <code>[]int</code>
and <code>[]int</code> must match <code>[]E</code> of the constraint,
a compiler can infer that <code>E</code> must be <code>int</code>.
Thus, for these two equations, type inference infers

        * Change *path operation decorators* parameter default for `response_model_exclude` from `set()` to `None` (as is in Pydantic).
    * In `encoders.jsonable_encoder`:
        * Remove deprecated `skip_defaults`, use instead `exclude_unset`.
        * Set default of `exclude` from `set()` to `None` (as is in Pydantic).
