    The FindStream class will emit the first chunk that matches a predicate, closing the source stream when it does

    var FindStream = PullStream.extend({
  constructor: function FindStream(source, cb) {
    PullStream.call(this, source);
    this._cb = cb;
  },

  _process: function(chunk) {
    if (this._cb(chunk)) {
      this._forward(chunk);
      this.pause();
      this.close();
    }
  }
});


module.exports = function find(cb) {
  return new FindStream(this, cb);
};
