Struct UPoly 

pub struct UPoly(/* private fields */);

A polynomial in one variable with real algebraic coefficients, lowest power first, with no trailing zero: a coordinate of a flight in the time since it began, an atom along a flight, a value along a tail in z.

Trait Implementations

impl Clone for UPoly

fn clone(&self) -> UPoly

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UPoly

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

Formats the value using the given formatter.

impl PartialEq for UPoly

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

fn lift(a: &Algebraic) -> Self

fn plus(&self, o: &Self) -> Result<Self, String>
