Types ¶
type Config ¶
type Config struct {
MaxRecvMsgSize int `yaml:"max_recv_msg_size"`
MaxSendMsgSize int `yaml:"max_send_msg_size"`
GRPCCompression string `yaml:"grpc_compression"`
RateLimit float64 `yaml:"rate_limit"`

BackoffConfig backoff.Config `yaml:"backoff_config"`
TLSEnabled bool `yaml:"tls_enabled"`
TLS tls.ClientConfig `yaml:",inline"`
SignWriteRequestsEnabled bool `yaml:"-"`
}
Config for a gRPC client.
func (*Config) CallOptions ¶
func (cfg *Config) CallOptions() []grpc.CallOption
CallOptions returns the config in terms of CallOptions.
func (*Config) DialOption ¶
func (cfg *Config) DialOption(unaryClientInterceptors []grpc.UnaryClientInterceptor, streamClientInterceptors []grpc.StreamClientInterceptor) ([]grpc.DialOption, error)
DialOption returns the config as a grpc.DialOptions.
func (*Config) RegisterFlags ¶
func (cfg *Config) RegisterFlags(f *flag.FlagSet)
RegisterFlags registers flags.
func (*Config) RegisterFlagsWithPrefix ¶ added in v1.1.0
func (cfg *Config) RegisterFlagsWithPrefix(prefix string, f *flag.FlagSet)
RegisterFlagsWithPrefix registers flags with prefix.
type SignRequest ¶ added in v1.16.0
type SignRequest interface {
// Sign returns the signature for the given request
Sign(context.Context) (string, error)
// VerifySign returns true if the signature is valid
VerifySign(context.Context, string) (bool, error)
}
SignRequest define the interface that must be implemented by the request structs to be signed
