Struct McapLoader 

pub struct McapLoader { /* private fields */ }

A DataLoader for MCAP files.

There are many different ways to extract and interpret information from MCAP files. For example, it might be interesting to query for particular fields of messages, or show information directly in the Rerun viewer. Because use-cases can vary, the McapLoader is made up of re_mcap::Layers, each representing different views of the underlying data.

These layers can be specified in the CLI wen converting an MCAP file to an .rrd. Here are a few examples:

• re_mcap::layers::McapProtobufLayer
• re_mcap::layers::McapRawLayer

Optionally, Lenses can be configured via Self::with_lenses to transform chunks as they are loaded (e.g., converting raw protobuf data into semantic Rerun components).

Implementations

impl McapLoader

pub fn new(selected_layers: SelectedLayers) -> Self

Creates a new McapLoader that extracts the specified layers.

pub fn with_raw_fallback(self, raw_fallback_enabled: bool) -> Self

Configures whether the raw layer is used as a fallback for unsupported channels.

pub fn with_lenses(self, lenses: Lenses) -> Self

Configures lenses to apply to chunks as they are loaded.

Trait Implementations

impl DataLoader for McapLoader

fn name(&self) -> DataLoaderName

Name of the DataLoader.

fn load_from_path( &self, settings: &DataLoaderSettings, path: PathBuf, tx: Sender<LoadedData>, ) -> Result<(), DataLoaderError>

Loads data from a file on the local filesystem and sends it to tx.

fn load_from_file_contents( &self, settings: &DataLoaderSettings, filepath: PathBuf, contents: Cow<'_, [u8]>, tx: Sender<LoadedData>, ) -> Result<(), DataLoaderError>

Loads data from in-memory file contents and sends it to tx.

impl Default for McapLoader

fn default() -> Self

Returns the “default value” for a type.
