# BagfileProgress.msg

## Overview

`BagfileProgress.msg` contains general information about the progress of bagfile processing. It is used to report how far a run over a set of input bagfiles has advanced, both in terms of messages and elapsed time.

## Fields

| Field | Type | Description |
| --- | --- | --- |
| `current_bagfile_name` | `string` | The name of the bagfile currently being processed. |
| `current_bagfile_id` | `uint32` | The index of the currently processed bagfile within the overall set. |
| `total_bagfiles` | `uint32` | The total number of bagfiles in the processing run. |
| `total_messages` | `uint32` | The total number of messages across all bagfiles. |
| `processed_messages` | `uint32` | The number of messages processed so far. |
| `total_seconds` | `float32` | The total expected duration of the bagfiles in seconds. |
| `processed_seconds` | `float32` | The amount of bagfile time processed so far in seconds. |

## Usage

- Consumers can compute progress as `processed_messages / total_messages` or `processed_seconds / total_seconds`.
- The message is self-contained: it reports absolute counts rather than deltas, so a consumer can reconstruct overall progress from any single sample.
