pub struct ExportFrame { /* private fields */ }Expand description
The rows an export writes. See DataTableState::export_frame.
Implementations§
Source§impl ExportFrame
impl ExportFrame
Source§impl ExportFrame
impl ExportFrame
Sourcepub const SOURCE_FILE_COLUMN: &'static str = "source_file"
pub const SOURCE_FILE_COLUMN: &'static str = "source_file"
The name of the column an export adds when asked to say where each row is from.
Sourcepub fn into_lazy(self) -> PolarsResult<LazyFrame>
pub fn into_lazy(self) -> PolarsResult<LazyFrame>
The plan. Naming the files reads the schema, which may resolve the scan, so this belongs off the UI thread.
The names are mapped from the row index batch by batch, so a streamed export still never holds every row.
