Struct Mono 

pub struct Mono { /* private fields */ }

A power product $\prod_i x_i^{e_i}$ (for example, $x^2y^5$). The variable part of a Poly term. Mono::cmp implements graded-lex ordering.

let a = mono!(x^2);
let b = mono!(x*y);
let c = mono!(x*z^2);
assert_eq!(a.mul(&b).mul(&c), mono!(x^4*y*z^2));

Trait Implementations

impl Clone for Mono

fn clone(&self) -> Mono

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mono

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

Formats the value using the given formatter.

impl Eq for Mono

impl Hash for Mono

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Mono

fn cmp(&self, other: &Self) -> Ordering

Graded-lex: total degree first; ties broken lexicographically on exponent vectors with lower Var index more significant (larger exponent on the first differing variable wins).

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Mono

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

impl PartialOrd for Mono

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
