Struct ChunkSchema

Source 
pub struct ChunkSchema {
    sorbet: SorbetSchema,
    row_id: RowIdColumnDescriptor,
    chunk_id: ChunkId,
    entity_path: EntityPath,
}
Expand description

The parsed schema of a Rerun chunk, i.e. multiple columns of data for a single entity.

This does NOT preserve custom arrow metadata. It only contains the metadata used by Rerun.
