Types

type ConfigLocks

type ConfigLocks struct {
	Bits int
	Tags map[string]struct{}
}

ConfigLocks records changing made by options that are not allowed further modifications.

func NewConfigLocks

func NewConfigLocks() *ConfigLocks

NewConfigLocks creates a ConfigLocks.

func (*ConfigLocks) ApplyLocks

func (cl *ConfigLocks) ApplyLocks(cfg rpcinfo.RPCConfig, svr remoteinfo.RemoteInfo)

ApplyLocks applies the locking operations on rpcinfo.RPCConfig and internal.RemoteInfo.

func (*ConfigLocks) Merge

func (cl *ConfigLocks) Merge(c2 *ConfigLocks)

Merge merges another ConfigLocks into the current one.

func (*ConfigLocks) Zero

func (cl *ConfigLocks) Zero()

Zero ConfigLocks clear

type Option

type Option struct {
	F func(o *Options, di *utils.Slice)
}

Option is the only way to config client.

type Options

type Options struct {
	Cli     *rpcinfo.EndpointBasicInfo
	Svr     *rpcinfo.EndpointBasicInfo
	Configs rpcinfo.RPCConfig
	Locks   *ConfigLocks
	Once    *configutil.OptionOnce

	MetaHandlers []remote.MetaHandler

	RemoteOpt        *remote.ClientOption
	Proxy            proxy.ForwardProxy
	Resolver         discovery.Resolver
	HTTPResolver     http.Resolver
	Balancer         loadbalance.Loadbalancer
	BalancerCacheOpt *lbcache.Options
	PoolCfg          *connpool2.IdleConfig
	ErrHandle        func(error) error
	Targets          string
	CBSuite          *circuitbreak.CBSuite
	Timeouts         rpcinfo.TimeoutProvider

	ACLRules []acl.RejectFunc

	MWBs  []endpoint.MiddlewareBuilder
	IMWBs []endpoint.MiddlewareBuilder

	Bus          event.Bus
	Events       event.Queue
	ExtraTimeout time.Duration

	// DebugInfo should only contains objects that are suitable for json serialization.
	DebugInfo    utils.Slice
	DebugService diagnosis.Service

	// Observability
	TracerCtl  *internal_stats.Controller
	StatsLevel *stats.Level

	// retry policy
	RetryPolicy    *retry.Policy
	RetryContainer *retry.Container

	CloseCallbacks []func() error
	WarmUpOption   *warmup.ClientOption

	// GRPC
	GRPCConnPoolSize uint32
	GRPCConnectOpts  *grpc.ConnectOptions
}

Options is used to initialize a client.

func NewOptions

func NewOptions(opts []Option) *Options

NewOptions creates a new option.

func (*Options) Apply

func (o *Options) Apply(opts []Option)

Apply applies all options.
