Module schema 

Schema helper for embedding a large Kubernetes core/v1 sub-object.

schemars inlines the entire structural schema of an embedded k8s-openapi type. The worst offender is the hooks JobSpec, which pulls in the full PodSpec: inlined, it makes a single SnapshotPolicy CRD ~1.2 MB (~85% of the whole bundle), which bloats Helm releases and breaks large-CRD apply paths (e.g. client-side apply’s 256 KB last-applied-configuration annotation limit).

preserve_unknown_object renders such a field as an opaque object the apiserver passes through verbatim (x-kubernetes-preserve-unknown-fields: true) instead of inlining its schema. The Rust field stays its concrete typed k8s-openapi type — kube still deserializes into it (so scalar type errors are still rejected at admission) and the apiserver structurally validates the actual object when the controller creates it (e.g. the hook Job at Job-creation time) — so only apply-time structural validation of that field is deferred.

Used only for the outsized hooks jobSpec (crate::snapshot_policy::RunJobHook). The smaller embedded core/v1 objects (mover/server securityContext, podSecurityContext, resources, affinity) are deliberately left inlined so the apiserver keeps validating them at apply time — the size they add is modest and the early validation is worth keeping for a backup operator.

Functions

preserve_unknown_object

Render an embedded core/v1 object field as { type: object, x-kubernetes-preserve-unknown-fields: true } rather than inlining its full k8s-openapi schema. Use via #[schemars(schema_with = "crate::schema::preserve_unknown_object")]. Reserved for the outsized hooks jobSpec; see the module docs for why the smaller embedded objects are left inlined.
