split a pull-stream into many substreams
var pull = require('pull-stream')
var pswitch = require('pull-switch')
pull(
pull.count(100),
pswitch(function select (e) {
// return key for which stream this is directed to.
return e % 2 ? 'even' : 'odd'
}, function createStream(key) { // 'even' or 'odd'
//return a stream that will be piped to...
return pull.drain(function (d) {
console.log(key+'>', d)
})
})
)
has the same api as pull-fork but reads the source at full power instead of trying to follow backpressure closely. In somecases it's simpler to do this, as waiting (for back-pressure to release) creates the possibility of deadlocks.
