Overview

Package quota is a generated protocol buffer package.

The `quota` template represents an item for which to check quota.

The `quota` template represents a piece of data to check Quota for.

When writing the configuration, the value for the fields associated with this template can either be a literal or an [expression](https://istio.io/docs/reference/config/mixer/expression-language.html). Please note that if the datatype of a field is not istio.mixer.adapter.model.v1beta1.Value, then the expression's [inferred type](https://istio.io/docs/reference/config/mixer/expression-language.html#type-checking) must match the datatype of the field.

Example config: ``` apiVersion: "config.istio.io/v1alpha2" kind: quota metadata: 

name: requestcount
namespace: istio-system

spec: 

dimensions:
  source: source.labels["app"] | source.service | "unknown"
  sourceVersion: source.labels["version"] | "unknown"
  destination: destination.labels["app"] | destination.service | "unknown"
  destinationVersion: destination.labels["version"] | "unknown"

```

type HandleQuotaServiceServer 

type HandleQuotaServiceServer interface {
	// HandleQuota is called by Mixer at request-time to deliver 'quota' instances to the backend.
	HandleQuota(context.Context, *HandleQuotaRequest) (*istio_mixer_adapter_model_v1beta11.QuotaResult, error)
}

type Handler 

type Handler interface {
	adapter.Handler

	// HandleQuota is called by Mixer at request time to deliver instances to
	// to an adapter.
	HandleQuota(context.Context, *Instance, adapter.QuotaArgs) (adapter.QuotaResult, error)
}

Handler must be implemented by adapter code if it wants to process data associated with the 'quota' template.

Mixer uses this interface to call into the adapter at request time in order to dispatch created instances to the adapter. Adapters take the incoming instances and do what they need to achieve their primary function.

The name of each instance can be used as a key into the Type map supplied to the adapter at configuration time via the method 'SetQuotaTypes'. These Type associated with an instance describes the shape of the instance

type HandlerBuilder 

type HandlerBuilder interface {
	adapter.HandlerBuilder

	// SetQuotaTypes is invoked by Mixer to pass the template-specific Type information for instances that an adapter
	// may receive at runtime. The type information describes the shape of the instance.
	SetQuotaTypes(map[string]*Type)
}

HandlerBuilder must be implemented by adapters if they want to process data associated with the 'quota' template.

Mixer uses this interface to call into the adapter at configuration time to configure it with adapter-specific configuration as well as all template-specific type information.

type Instance 

type Instance struct {
	// Name of the instance as specified in configuration.
	Name string

	// The unique identity of the particular quota to manipulate.
	Dimensions map[string]interface{}
}

Instance is constructed by Mixer for the 'quota' template.

The `quota` template represents a piece of data to check Quota for.

When writing the configuration, the value for the fields associated with this template can either be a literal or an [expression](https://istio.io/docs/reference/config/mixer/expression-language.html). Please note that if the datatype of a field is not istio.mixer.adapter.model.v1beta1.Value, then the expression's [inferred type](https://istio.io/docs/reference/config/mixer/expression-language.html#type-checking) must match the datatype of the field.

Example config: ``` apiVersion: "config.istio.io/v1alpha2" kind: quota metadata: 

name: requestcount
namespace: istio-system

spec: 

dimensions:
  source: source.labels["app"] | source.service | "unknown"
  sourceVersion: source.labels["version"] | "unknown"
  destination: destination.labels["app"] | destination.service | "unknown"
  destinationVersion: destination.labels["version"] | "unknown"

```

type InstanceMsg 

type InstanceMsg struct {
	// Name of the instance as specified in configuration.
	Name string `protobuf:"bytes,72295727,opt,name=name,proto3" json:"name,omitempty"`
	// The unique identity of the particular quota to manipulate.
	Dimensions map[string]*istio_mixer_adapter_model_v1beta12.Value `` /* 147-byte string literal not displayed */
}

Contains instance payload for 'quota' template. This is passed to infrastructure backends during request-time through HandleQuotaService.HandleQuota.

}
