Functions

func GetClientOptions 

func GetClientOptions(ops []Option) []client.Option

GetClientOptions converts given streamclient.Option(s) to client.Option(s)

Types

type Option 

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

func ConvertOptionFrom deprecated 

func ConvertOptionFrom(opt client.Option) Option

Deprecated: it's not supposed to be called by users directly; may be removed in future versions. ConvertOptionFrom converts client.Option to streamclient.Option It's convenient for creating StreamOption from existing client.Option Note: NOT all client.Option(s) converted will work for stream clients; Even if it works for now, it's NOT guaranteed that it will always work for future versions.

func WithACLRules 

func WithACLRules(rules ...acl.RejectFunc) Option

func WithGRPCConnPoolSize 

func WithGRPCConnPoolSize(s uint32) Option

WithGRPCConnPoolSize sets the value for the client connection pool size.

func WithGRPCInitialConnWindowSize 

func WithGRPCInitialConnWindowSize(s uint32) Option

WithGRPCInitialConnWindowSize sets the value for initial window size on a connection of grpc. The lower bound for window size is 64K and any value smaller than that will be ignored. It corresponds to the WithInitialConnWindowSize DialOption of gRPC.

func WithGRPCInitialWindowSize 

func WithGRPCInitialWindowSize(s uint32) Option

WithGRPCInitialWindowSize sets the value for initial window size on a grpc stream. The lower bound for window size is 64K and any value smaller than that will be ignored. It corresponds to the WithInitialWindowSize DialOption of gRPC.

func WithGRPCKeepaliveParams 

func WithGRPCKeepaliveParams(kp grpc.ClientKeepalive) Option

WithGRPCKeepaliveParams returns a DialOption that specifies keepalive parameters for the client transport. It corresponds to the WithKeepaliveParams DialOption of gRPC.

func WithGRPCMaxHeaderListSize 

func WithGRPCMaxHeaderListSize(s uint32) Option

WithGRPCMaxHeaderListSize returns a DialOption that specifies the maximum (uncompressed) size of header list that the client is prepared to accept. It corresponds to the WithMaxHeaderListSize DialOption of gRPC.

func WithGRPCReadBufferSize 

func WithGRPCReadBufferSize(s uint32) Option

WithGRPCReadBufferSize lets you set the size of read buffer, this determines how much data can be read at most for each read syscall.

func WithGRPCTLSConfig 

func WithGRPCTLSConfig(tlsConfig *tls.Config) Option

WithGRPCTLSConfig sets the TLS config for gRPC client.

func WithGRPCWriteBufferSize 

func WithGRPCWriteBufferSize(s uint32) Option

WithGRPCWriteBufferSize determines how much data can be batched before writing on the wire. The corresponding memory allocation for this buffer will be twice the size to keep syscalls low. The default value for this buffer is 32KB.

func WithHTTPResolver 

func WithHTTPResolver(r http.Resolver) Option
