pub struct StructuralBatchDecodeStream { /* private fields */ }Expand description
A stream that takes scheduled jobs and generates decode tasks from them.

Create a new instance of a batch decode stream
§Arguments
scheduled- an incoming stream of decode tasks from a [crate::decode::DecodeBatchScheduler]schema- the schema of the data to createrows_per_batchthe number of rows to create before making a batchnum_rowsthe total number of rows schedulednum_columnsthe total number of columns in the file
