Struct SuperTableV 

pub struct SuperTableV {
    pub slices: Vec<TableV>,
    pub len: usize,
}

SuperTableView

Borrowed view over [offset .. offset + len) rows from a SuperTable, potentially spanning multiple table batches (TableV slices).

Purpose

• Mini-batch representation of a single logical Table or SuperTable batch.
• Allows preserving cached metadata (e.g. null counts) across multiple regions without merging or cloning data.

Fields

• slices: constituent TableV slices covering the window.
• len: logical row count of this view.

Notes

• Use chunks / iter for slice-level access.
• Random row access via row / row_slice.
• Create smaller windows via slice without data copies.

Fields

slices: Vec<TableV>

len: usize

Implementations

impl SuperTableV

pub fn is_empty(&self) -> bool

pub fn n_slices(&self) -> usize

pub fn cols(&self) -> Vec<Arc<Field>>

Returns the columns of the Super Table

Holds an assumption that all inner tables have the same fields

pub fn chunks(&self) -> impl Iterator<Item = &TableV>

Iterator over slice‐level TableSlices.

pub fn slice(&self, offset: usize, len: usize) -> SuperTableV

Returns a sub-window of this chunked slice object as a new ChunkedTableSlice.

pub fn row(&self, row_idx: usize) -> TableV

Random-access a single row (as a zero-copy TableSlice of length 1).

pub fn iter(&self) -> impl Iterator<Item = TableV>

Iterate through all TableSlices in this slice.

pub fn row_slice(&self, row: usize) -> TableV

Return a zero-copy TableSlice of exactly one row by global row index.

pub fn n_rows(&self) -> usize

Returns the total number of rows in the Super table across all chunks

pub fn n_cols(&self) -> usize

Returns the number of columns in the Super table.

Assumes that every chunk has the same column schema as per the semantic requirement.

Trait Implementations

impl Clone for SuperTableV

fn clone(&self) -> SuperTableV

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Concatenate for SuperTableV

fn concat(self, other: SuperTableV) -> Result<SuperTableV, MinarrowError>

Concatenates two super table views by materialising both to owned tables, concatenating them, and wrapping the result back in a view.

Notes

• This operation copies data from both views to create owned tables.
• The resulting view contains a single slice wrapping the concatenated table.

impl Consolidate for SuperTableV

fn consolidate(self) -> Table

Consolidates all view slices into a single contiguous Table.

Creates a SuperTable from the views and consolidates it. The result table is named “part” to indicate it’s a partial/consolidated view.

type Output = Table

The type produced after consolidation.

impl Debug for SuperTableV

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl From<SuperTable> for SuperTableV

Available on crate feature chunked only.

fn from(super_table: SuperTable) -> SuperTableV

Converts to this type from the input type.

impl From<SuperTableV> for SuperTable

Available on crate feature views only.

fn from(super_table_v: SuperTableV) -> SuperTable

Converts to this type from the input type.

impl Shape for SuperTableV

fn shape(&self) -> ShapeDim

Returns arbitrary Shape dimension for any data shape

fn shape_1d(&self) -> usize

Returns the first dimension shape

fn shape_2d(&self) -> (usize, usize)

Returns the first and second dimension shapes

fn shape_3d(&self) -> (usize, usize, usize)

Returns the first, second and third dimension shapes

fn shape_4d(&self) -> (usize, usize, usize, usize)

Returns the first, second, third and fourth dimension shapes
