OpenTelemetry tracing for [Broadway](https://elixir-broadway.org/) pipelines.

## Usage

After installing, set up the handler in your application's `Application.start/2` callback, before your top-level supervisor starts:

```elixir
def start(_type, _args) do
  OpentelemetryBroadway.setup()

  Supervisor.start_link(...)
end
```

## Installation

This library is available on Hex:

```elixir
defp deps do
  [
    {:opentelemetry_broadway, "~> 0.1"}
  ]
end
```
