Helper trait for converting ObjectMeta into useful PartialObjectMeta variants

Required Methods

fn into_request_partial<K: Resource<DynamicType = ()>>( self ) -> PartialObjectMeta<K>

Convert ObjectMeta into a Patch-serializable PartialObjectMeta

This object can be passed to Patch::Apply and used with Api::patch_metadata, for an Api<K> using the underlying types TypeMeta:

let partial = ObjectMeta {
    labels: Some([("key".to_string(), "value".to_string())].into()),
    ..Default::default()
}.into_request_partial::<Pod>();

// request partials are generally closer to patches than fully valid resources:
assert_eq!(partial.name_any(), "");

// typemeta is re-used from K:
assert_eq!(partial.types.unwrap().kind, "Pod");

fn into_response_partial<K>(self) -> PartialObjectMeta<K>

Convert ObjectMeta into a response object for a specific Resource

This object emulates a response object and cannot be used in request bodies because it contains erased TypeMeta (and the apiserver is doing the erasing).

This method is mostly useful for unit testing behaviour.

let partial = ObjectMeta {
    name: Some("my-deploy".to_string()),
    namespace: Some("default".to_string()),
    ..Default::default()
}.into_response_partial::<Deployment>();

assert_eq!(partial.name_any(), "my-deploy");
assert_eq!(partial.types.unwrap().kind, "PartialObjectMetadata"); // NB: Pod erased

Object Safety

This trait is not object safe.
