In OkHttp some fields of the address come from the URL (scheme, hostname, port) and the rest come from the [OkHttpClient](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-ok-http-client/).

# Go references to C

Within the Go file, C's struct field names that are keywords in Go
can be accessed by prefixing them with an underscore: if x points at a C
struct with a field named "type", x._type accesses the field.
C struct fields that cannot be expressed in Go, such as bit fields
or misaligned data, are omitted in the Go struct, replaced by
appropriate padding to reach the next field or the end of the struct.

  * Previously this would cause the command to fail regardless of whether or not the field was present in the object model
  * Now the command will succeed even if the sort-by field is missing from one or more of the objects

The `IstioOperatorSpec` API fields are translated to the output manifest in two ways:

1. The `IstioOperatorSpec` API fields are mapped to the Helm values.yaml schema using the
[APIMapping](https://github.com/istio/operator/blob/e9097258cb4fbe59648e7da663cdad6f16927b8f/pkg/translate/translate.go#L112)

            fields will be ignored at serialization time.
