RrdFooter

rerun::external::re_log_encoding

Struct RrdFooter 

Source 
pub struct RrdFooter {
    pub manifests: HashMap<StoreId, RawRrdManifest>,
}
Expand description

This is the payload that is carried in messages of type ::End in RRD streams.

It keeps track of various useful information about the associated recording.

During normal operations, there can only be a single ::End message in an RRD stream, and therefore a single RrdFooter. It is possible to break that invariant by concatenating streams using external tools, e.g. by doing something like cat *.rrd > all_my_recordings.rrd. Passing that stream back through Rerun tools, e.g. cat *.rrd | rerun rrd merge > all_my_recordings.rrd, would once again guarantee that only one ::End message is present though. I.e. that invariant holds as long as one stays within our ecosystem of tools.

This is an application-level type, the associated transport-level type can be found over at re_protos::log_msg::v1alpha1::RrdFooter.

Fields§

§manifests: HashMap<StoreId, RawRrdManifest>

All the RawRrdManifests that were found in this RRD footer.

Each RawRrdManifest corresponds to one, and exactly one, RRD stream (i.e. recording).

The order is unspecified.
