Struct RawExtension

pub struct RawExtension(pub Value);

RawExtension is used to hold extensions in external versions.

To use this, make a field which has RawExtension as its type in your external, versioned struct, and Object in your internal struct. You also need to register your various plugin types.

// Internal package:

type MyAPIObject struct { runtime.TypeMeta json:",inline" MyPlugin runtime.Object json:"myPlugin" }

type PluginA struct { AOption string json:"aOption" }

// External package:

type MyAPIObject struct { runtime.TypeMeta json:",inline" MyPlugin runtime.RawExtension json:"myPlugin" }

type PluginA struct { AOption string json:"aOption" }

// On the wire, the JSON will look something like this:

{ “kind”:“MyAPIObject”, “apiVersion”:“v1”, “myPlugin”: { “kind”:“PluginA”, “aOption”:“foo”, }, }

So what happens? Decode first uses json or yaml to unmarshal the serialized data into your external MyAPIObject. That causes the raw JSON to be stored, but not unpacked. The next step is to copy (using pkg/conversion) into the internal struct. The runtime package’s DefaultScheme has conversion functions installed which will unpack the JSON stored in RawExtension, turning it into the correct object type, and storing it in the Object. (TODO: In the case where the object is of an unknown type, a runtime.Unknown object will be created and stored.)

Trait Implementations

impl Clone for RawExtension

fn clone(&self) -> RawExtension

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RawExtension

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

Formats the value using the given formatter.

impl DeepMerge for RawExtension

fn merge_from(&mut self, other: Self)

Merge other into self.

impl Default for RawExtension

fn default() -> RawExtension

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RawExtension

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RawExtension

fn eq(&self, other: &RawExtension) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for RawExtension

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
