type RaftClient 

type RaftClient interface {
	RequestVote(ctx context.Context, in *VoteRequest, opts ...grpc.CallOption) (*VoteReply, error)
	AppendEntries(ctx context.Context, opts ...grpc.CallOption) (Raft_AppendEntriesClient, error)
}

RaftClient is the client API for Raft service.

For semantics around ctx use and closing/ending streaming RPCs, please refer to https://pkg.go.dev/google.golang.org/grpc/?tab=doc#ClientConn.NewStream.

func NewRaftClient 

func NewRaftClient(cc grpc.ClientConnInterface) RaftClient

type RaftServer 

type RaftServer interface {
	RequestVote(context.Context, *VoteRequest) (*VoteReply, error)
	AppendEntries(Raft_AppendEntriesServer) error
	// contains filtered or unexported methods
}

RaftServer is the server API for Raft service. All implementations must embed UnimplementedRaftServer for forward compatibility

type Raft_AppendEntriesClient 

type Raft_AppendEntriesClient interface {
	Send(*AppendRequest) error
	Recv() (*AppendReply, error)
	grpc.ClientStream
}

type Raft_AppendEntriesServer 

type Raft_AppendEntriesServer interface {
	Send(*AppendReply) error
	Recv() (*AppendRequest, error)
	grpc.ServerStream
}

type UnimplementedRaftServer 

type UnimplementedRaftServer struct {
}

UnimplementedRaftServer must be embedded to have forward compatible implementations.

func (UnimplementedRaftServer) AppendEntries 

func (UnimplementedRaftServer) AppendEntries(Raft_AppendEntriesServer) error

func (UnimplementedRaftServer) RequestVote 

func (UnimplementedRaftServer) RequestVote(context.Context, *VoteRequest) (*VoteReply, error)

type UnsafeRaftServer 

type UnsafeRaftServer interface {
	// contains filtered or unexported methods
}

UnsafeRaftServer may be embedded to opt out of forward compatibility for this service. Use of this interface is not recommended, as added methods to RaftServer will result in compilation errors.

type VoteReply 

type VoteReply struct {
	Remote  uint32 `protobuf:"varint,1,opt,name=remote,proto3" json:"remote,omitempty"`   // the PID of the voter
	Term    uint64 `protobuf:"varint,2,opt,name=term,proto3" json:"term,omitempty"`       // the current term of voter
