Struct nexsys_core::Equation

pub struct Equation { /* private fields */ }

Represents an equation and gives info about its known and unknown variables

Implementations

impl Equation

pub fn new(text: &str) -> Equation

Initializes a new Equation struct

pub fn as_expr(&self) -> String

Returns the equation as an expression that evaluates to 0 when the system is solved.

pub fn as_text(&self) -> String

Returns the equation as a &str.

pub fn vars(&self) -> Vec<String>

Returns a list of variables used in the equation

pub fn n_unknowns(&self, ctx: &HashMap<String, Variable>) -> usize

Returns the number of unknown variables in the equation.

pub fn unknowns(&self, ctx: &HashMap<String, Variable>) -> Vec<String>

Returns a Vec containing the variables that are unknowns in the equation.

Trait Implementations

impl Clone for Equation

fn clone(&self) -> Equation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Equation

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

Formats the value using the given formatter.

impl PartialEq<Equation> for Equation

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

This method tests for self and other values to be equal, and is used by ==.

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

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