Struct ExtGroup 

pub struct ExtGroup {
    pub degree: usize,
    pub rank: usize,
    pub torsion: Vec<u64>,
}

A single Ext group Ext^n_R(M, N).

Fields

degree: usize

Cohomological degree n.

rank: usize

Free rank.

torsion: Vec<u64>

Torsion summands.

Implementations

impl ExtGroup

pub fn new(degree: usize, rank: usize) -> Self

Create an Ext group.

pub fn is_zero(&self) -> bool

True iff the Ext group is zero.

Trait Implementations

impl Clone for ExtGroup

fn clone(&self) -> ExtGroup

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExtGroup

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

Formats the value using the given formatter.

impl Display for ExtGroup

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

Formats the value using the given formatter.

impl PartialEq for ExtGroup

fn eq(&self, other: &ExtGroup) -> 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.
