roboto.formats.fields
Module Contents
FieldSelection
A field to read out of a data file, identified by its path through the schema.
The roboto.formats readers take the fields to read as FieldSelection values; to_field_selection() converts a topic’s message path into one.
Attributes
FieldSelection.path_in_schema
Path components locating this field in the source data schema, root to leaf.
A component may contain dots, so ("header", "stamp") (a stamp field nested in a header struct) and ("header.stamp",) (a top-level column named header.stamp) are different fields.
