Enum Patch 

pub enum Patch {
    Merge(Value),
    Strategic(Value),
    Json(Vec<JsonPatchOp>),
    Apply {
        field_manager: String,
        force: bool,
        body: Value,
    },
}

A patch operation against an existing resource.

Variants

Merge(Value)

JSON Merge Patch (RFC 7396). Content-Type: application/merge-patch+json. The simplest variant — replace fields named in the patch, leave others alone.

Strategic(Value)

Strategic Merge Patch — Kubernetes-specific, knows how to merge arrays of objects (e.g. containers) by key. Content-Type: application/strategic-merge-patch+json. Default for kubectl patch without --type.

Json(Vec<JsonPatchOp>)

JSON Patch (RFC 6902) — list of add/remove/replace ops. Content-Type: application/json-patch+json.

Apply

Server-Side Apply — declarative reconciliation with apiserver- side field-ownership tracking. Content-Type: application/apply-patch+yaml. Carries the field-manager id the caller speaks for.

Fields

field_manager: String

Identity of the caller doing the apply (e.g. engenho-scheduler).

force: bool

Whether to take ownership of conflicting fields (rare).

body: Value

The (possibly partial) resource state we’re declaring.

Implementations

impl Patch

pub fn content_type(&self) -> &'static str

The HTTP Content-Type header value the apiserver expects for this patch variant.

pub fn body_bytes(&self) -> Result<Vec<u8>, Error>

Serialize the patch body to a Vec<u8> ready for the request.

Errors

Returns the underlying serde_json error if serialization fails (effectively unreachable — all our variants are owned-data).

Trait Implementations

impl Clone for Patch

fn clone(&self) -> Patch

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Patch

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Patch

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Patch

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
