Modules

cdr

CDR (Common Data Representation) decoding utilities for DDS-RTPS messages.

decoders

Structs

McapChannelInfo

Structured information about one MCAP channel.

McapChunkInfo

Aggregate information about indexed MCAP chunks.

McapCompressionInfo

Aggregate information for one MCAP chunk compression codec.

McapFile

An immutable view of an MCAP file’s bytes with lazily cached file-level information.

McapInfo

Header and summary information about an MCAP file.

McapSchemaInfo

Schema metadata referenced by an MCAP channel.

ParserContext

Common context used by parsers to build timelines and store entity paths.

ScanResult

The result of a cheap, decompression-free scan of an MCAP data section.

Summary

Indexes of an MCAP file parsed from its (optional) summary section

Enums

Error

The base error type for handling MCAP files.

ImageEncoding

A raw image encoding string, as used by ROS and Foxglove.

McapSummarySource

Whether the summary backing an McapInfo came from the file or was reconstructed.

Traits

MessageParser

Trait for parsing MCAP messages of a specific schema into Rerun chunks.

Functions

build_chunk_index

Cheaply scans the data section of an MCAP file, reconstructing its chunk + metadata index.

decode_image_encoding

Parses a raw image encoding string (shared by ROS and Foxglove) into an ImageEncoding.

decode_image_format

Decodes a raw image encoding string (shared by ROS and Foxglove) into a Rerun ImageFormat.

read_or_reconstruct_summary

Reads an MCAP Summary, falling back to reconstruct_summary when recover is set and the file has no valid summary.

read_summary

Read out the summary of an MCAP file.
