Struct Term 

pub struct Term<const NUM_VARIABLES: usize> { /* private fields */ }

Represents a single term in a polynomial with NUM_VARIABLES variables.

A term consists of a coefficient and an array of VarFunctions, each applied to a corresponding variable in the input.

For example, for NUM_VARIABLES = 2:

use const_poly::{Term, VarFunction::*};
const TERM: Term<2> = Term::new(3.0, [Sin, Pow(2)]);

represents the term 3 * sin(x_0) * (x_1)^2.

Implementations

impl<const NUM_VARIABLES: usize> Term<NUM_VARIABLES>

pub const fn new( coefficient: f64, functions: [VarFunction; NUM_VARIABLES], ) -> Self

Creates a new Term with the specified coefficient and functions.

Parameters

• coefficient: The scalar multiplier for the term.
• functions: An array of VarFunctions, one per variable.

Returns

A new Term instance.

Example

use const_poly::{Term, VarFunction::*};
const TERM: Term<2> = Term::new(2.0, [Sin, Pow(3)]);

represents the term 2.0 * sin(x_0) * (x_1)^3.

pub const fn evaluate(&self, vars: [f64; NUM_VARIABLES]) -> f64

Evaluates the term for the given variables.

Applies each function in functions to the corresponding variable, then multiplies all results together with the coefficient.

Parameters

• vars: An array of variables of length NUM_VARIABLES.

Returns

The floating-point result of evaluating the term.

Example

use const_poly::{Term, VarFunction::*};
const TERM: Term<1> = Term::new(2.0, [Sin]);
const val: f64 = TERM.evaluate([1.57079632679]); // Approx sin(pi/2)
assert!((val - 2.0).abs() < 1e-6);
