Struct RowView 

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

A view into a single logical row of a factorized chunk.

Provides zero-copy access to values at each level without materializing the entire row.

Implementations

impl<'a> RowView<'a>

pub fn new(chunk: &'a FactorizedChunk, indices: RowIndices) -> Self

Creates a new row view.

pub fn from_ref(chunk: &'a FactorizedChunk, indices: &RowIndices) -> Self

Creates a new row view from a reference to indices (clones the indices).

pub fn get(&self, level: usize, column: usize) -> Option<Value>

Gets a value at a specific level and column.

pub fn get_node_id(&self, level: usize, column: usize) -> Option<NodeId>

Gets a NodeId at a specific level and column.

pub fn get_edge_id(&self, level: usize, column: usize) -> Option<EdgeId>

Gets an EdgeId at a specific level and column.

pub fn level_count(&self) -> usize

Returns the number of levels in this row.

pub fn values(&self) -> impl Iterator<Item = Value> + '_

Returns an iterator over all values in this row.

Values are yielded in order: all columns at level 0, then level 1, etc.

pub fn to_vec(&self) -> Vec<Value>

Materializes this row into a vector of values.

Trait Implementations

impl<'a> Clone for RowView<'a>

fn clone(&self) -> RowView<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for RowView<'a>

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

Formats the value using the given formatter.
