# `Adbc.StreamResult`
[🔗](https://github.com/elixir-explorer/adbc/blob/v0.9.0/lib/adbc_result.ex#L1)

Represents an unmaterialized Arrow stream from a query.

This struct can only be used within the callback passed to
`Adbc.Connection.query_pointer/4`. The stream can only be consumed
**once** - after being passed to `bulk_insert/3` or other operations,
it becomes invalid.

It contains:

  * `:ref` - internal reference to the stream (do not use directly)
  * `:conn` - internal connection pid (do not use directly)
  * `:pointer` - pointer to the ArrowArrayStream (integer memory address)
  * `:num_rows` - the number of rows affected by the query, may be `nil`
    for queries depending on the database driver

# `t`

```elixir
@type t() :: %Adbc.StreamResult{
  conn: pid(),
  num_rows: non_neg_integer() | nil,
  pointer: non_neg_integer(),
  ref: reference()
}
```
