Struct RemainingRowGroupsParts 

pub(crate) struct RemainingRowGroupsParts {
    pub schema: SchemaRef,
    pub metadata: Arc<ParquetMetaData>,
    pub row_groups: Vec<usize>,
    pub selection: Option<RowSelection>,
    pub offset: Option<usize>,
    pub limit: Option<usize>,
    pub reader_builder: RowGroupReaderBuilderParts,
}

The state recovered from a RemainingRowGroups by RemainingRowGroups::into_parts, describing the row groups not yet decoded so a builder reconstructed from it resumes where the decoder left off.

Fields

schema: SchemaRef

The arrow schema of the decoded output.

metadata: Arc<ParquetMetaData>

The Parquet file metadata.

row_groups: Vec<usize>

Row groups not yet handed to the reader builder.

selection: Option<RowSelection>

The not-yet-consumed slice of the global row selection.

offset: Option<usize>

Offset still to be skipped before the next readable row group.

limit: Option<usize>

Output rows still permitted across the remaining row groups.

reader_builder: RowGroupReaderBuilderParts

Builder-configurable parts of the inner row-group reader builder.
