Examples

Before running the examples, move to the installation directory of Speer:

cd $GOPATH/src/github.com/danalex97/Speer

We provide the following examples:

go run speer.go -config=examples/config/sink.json
go run speer.go -config=examples/config/broadcast.json
go run speer.go -config=examples/config/data_link.json

For a more complex example, check this repository.

Primitives

Getting the bootstrap node id:

id := util.Join()

Sending a control message:

util.Transport().ControlSend(id, "message")

Receiving a control message:

msg := <-util.Transport().ControlRecv()

Sending data via a link:

// Creating the link
link := util.Transport().Connect(id)

// Sending the data
link.Upload(Data{
  Id   : "someUniqueId", // Some ID associated with the message.
                         // The ID can be used for keeping the actual data or metadata.
  Size : 1000, // Total data size in bits.
})

Getting data from a link:

data := <-link.Download()

Setting up a callback:

util.Callback(100, func() {
    // [...]
})

Setting up a periodic routine:

util.Routine(100, func() {
    // [...]
})
