Crate rosbag

Utilities for efficient reading of ROS bag files.

Example

use rosbag::{ChunkRecord, MessageRecord, IndexRecord, RosBag};

let bag = RosBag::new(path)?;
// Iterate over records in the chunk section
for record in bag.chunk_records() {
    match record? {
        ChunkRecord::Chunk(chunk) => {
            // iterate over messages in the chunk
            for msg in chunk.messages() {
                match msg? {
                    MessageRecord::MessageData(msg_data) => {
                        // ..
                    }
                    MessageRecord::Connection(conn) => {
                        // ..
                    }
                }
            }
        },
        ChunkRecord::IndexData(index_data) => {
            // ..
        },
    }
}
// Iterate over records in the index section
for record in bag.index_records() {
    match record? {
        IndexRecord::IndexData(index_data) => {
            // ..
        }
        IndexRecord::Connection(conn) => {
            // ..
        }
        IndexRecord::ChunkInfo(chunk_info) => {
            // ..
        }
    }
}
