Struct FinExtYoungShape 

pub struct FinExtYoungShape {
    pub parts: Vec<usize>,
}

Young tableau shape: a partition of n stored as a non-increasing sequence.

Fields

parts: Vec<usize>

The partition: parts[i] is the length of the i-th row.

Implementations

impl FinExtYoungShape

pub fn new(parts: Vec<usize>) -> Option<Self>

Create a Young shape from a partition (must be non-increasing).

pub fn size(&self) -> usize

The total number of cells (size of the partition).

pub fn rows(&self) -> usize

Number of rows.

pub fn row_len(&self, i: usize) -> usize

Length of row i (0-indexed).

pub fn conjugate(&self) -> Self

The conjugate (transpose) partition.

pub fn is_valid(&self) -> bool

Check if this shape is a valid Young diagram (non-increasing rows).

pub fn hook_length_count(&self) -> u64

Count standard Young tableaux using the hook length formula.

Trait Implementations

impl Clone for FinExtYoungShape

fn clone(&self) -> FinExtYoungShape

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FinExtYoungShape

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

Formats the value using the given formatter.

impl PartialEq for FinExtYoungShape

fn eq(&self, other: &FinExtYoungShape) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
