```go theme={"system"}
func CollectAs[T proto.Message](seq iter.Seq2[[]byte, error]) ([]T, error)
```

Convert a sequence of bytes into a slice of `proto.Message`.

Useful to convert the output of [`Datapoints.Query`](/api-reference/go/datasets/Datapoints.Query) into a slice of `proto.Message`.

This a convenience function for `Collect(As[T](seq))`.

## Parameters

<ParamField path="seq" type="iter.Seq2[[]byte, error]">
  The sequence of bytes to convert
</ParamField>

## Returns

A slice of `proto.Message` or an error if any.
