Struct PanelSliceTemplate 

pub struct PanelSliceTemplate<'a> { /* private fields */ }

Per-unit offsets into a stacked panel table, plus payload pointers of the baseline stacked columns so a later mutation can reuse original unit Arcs.

Implementations

impl<'a> PanelSliceTemplate<'a>

pub fn from_panel( original: &'a PanelData, stacked: &TabularData, ) -> Result<Self, ValidationError>

Compile offsets and baseline stacked-column identity from original + stacked.

stacked must be the pre-mutation concatenation of original (same row count).

Errors

Row-count mismatch, or a unit whose column count disagrees with the panel schema.

pub fn apply_stacked( &self, stacked: &TabularData, ) -> Result<PanelData, ValidationError>

Rebuild a panel from a (possibly mutated / column-appended) stacked table.

Unmutated columns whose stacked payload pointer still matches the baseline reuse the original per-unit OwnedColumn Arc. Mutated and appended columns are sliced from stacked.

Errors

Row-count mismatch, out-of-range slice, or a non-float mutated column.
