class roboto.formats.fields.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.

path_in_schema: tuple[str, ...]

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.
