Struct FactorizationLevel 

pub struct FactorizationLevel { /* private fields */ }

A factorization level containing columns at the same nesting depth.

Implementations

impl FactorizationLevel

pub fn flat(columns: Vec<FactorizedVector>, column_names: Vec<String>) -> Self

Creates a new flat level (level 0) from columns.

pub fn unflat( columns: Vec<FactorizedVector>, column_names: Vec<String>, multiplicities: Vec<usize>, ) -> Self

Creates a new unflat level with the given multiplicities.

Note: multiplicities[i] is the number of values for parent i. The total number of values (group_count) is the sum of all multiplicities.

pub fn column_count(&self) -> usize

Returns the number of columns at this level.

pub fn group_count(&self) -> usize

Returns the number of groups at this level.

pub fn physical_value_count(&self) -> usize

Returns the total physical value count across all columns.

pub fn multiplicities(&self) -> &[usize]

Returns the multiplicities for this level.

pub fn column(&self, index: usize) -> Option<&FactorizedVector>

Returns a column by index.

pub fn column_mut(&mut self, index: usize) -> Option<&mut FactorizedVector>

Returns a mutable column by index.

pub fn column_names(&self) -> &[String]

Returns the column names.

impl Clone for FactorizationLevel

fn clone(&self) -> FactorizationLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FactorizationLevel

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