# `Explorer.Backend.QueryFrame`
[🔗](https://github.com/elixir-nx/explorer/blob/v0.12.0/lib/explorer/backend/query_frame.ex#L1)

Represents a lazy dataframe for building query expressions.

You may call `Explorer.Query.new` to create a query-backed dataframe.
The QueryFrame is available inside `filter_with`, `mutate_with`, and
similar. You cannot perform any operation on them except accessing
its underlying series.

# `t`

```elixir
@type t() :: %Explorer.Backend.QueryFrame{
  backend: module(),
  dtypes: Explorer.Backend.DataFrame.dtypes(),
  names: Explorer.Backend.DataFrame.column_name(),
  resource: reference() | nil
}
```
