Example 
package main

import (
	"context"

	"go.thethings.network/lorawan-stack/pkg/auth/rights"
	"go.thethings.network/lorawan-stack/pkg/ttnpb"
)

func main() {
	var ( // Assume these come from a hypothetical Set RPC call.
		ctx context.Context
		dev ttnpb.EndDevice
	)

	if err := rights.RequireApplication(ctx, dev.ApplicationIdentifiers, ttnpb.RIGHT_APPLICATION_DEVICES_WRITE); err != nil {
		// return nil, err
	}
}

Output:

Types

type Fetcher 

type Fetcher interface {
	ApplicationRights(context.Context, ttnpb.ApplicationIdentifiers) (*ttnpb.Rights, error)
	ClientRights(context.Context, ttnpb.ClientIdentifiers) (*ttnpb.Rights, error)
	GatewayRights(context.Context, ttnpb.GatewayIdentifiers) (*ttnpb.Rights, error)
	OrganizationRights(context.Context, ttnpb.OrganizationIdentifiers) (*ttnpb.Rights, error)
	UserRights(context.Context, ttnpb.UserIdentifiers) (*ttnpb.Rights, error)
}

Fetcher interface for rights fetching.

func NewAccessFetcher 

func NewAccessFetcher(getConn func(ctx context.Context) *grpc.ClientConn, allowInsecure bool) Fetcher

NewAccessFetcher returns a new rights fetcher that fetches from the Access role returned by getConn. The allowInsecure argument indicates whether it's allowed to send credentials over connections without TLS.

func NewInMemoryCache 

func NewInMemoryCache(fetcher Fetcher, successTTL, errorTTL time.Duration) Fetcher

NewInMemoryCache returns a new in-memory cache on top of the given fetcher. Successful responses are valid for the duration of successTTL, unsuccessful responses are valid for the duration of errorTTL.

type FetcherFunc 

type FetcherFunc func(ctx context.Context, ids ttnpb.Identifiers) (*ttnpb.Rights, error)

FetcherFunc is a function that implements the Fetcher interface.

A FetcherFunc that returns all Application rights for any Application, would look like this: 

fetcher := rights.FetcherFunc(func(ctx context.Context, ids ttnpb.Identifiers) (*ttnpb.Rights, error) {
	rights := ttnpb.AllApplicationRights // Instead this usually comes from an identity server or a database.
	return &rights, nil
})
