Struct Sequence

Source

pub struct Sequence(pub Number, pub Number);

Expand description

A sequence, represented by the two starting values, which are later used to compute further values

Implementations§

Source §

impl Sequence

Source

pub fn new(sequence: impl Into<Self>) -> Self

Creates a new sequence with the given starting values

§Examples

Sequence::new([1,1]);

Source

pub fn fibonacci() -> Self

Returns the fibonacci sequence, represented as a Sequence struct

§Examples

let sequence = Sequence::new([1, 1]);
let fib_sequence = Sequence::fibonacci();

assert_eq!(sequence, fib_sequence);

Source

pub fn calculate(self, n: usize) -> Number

Calculate the nth term of the sequence

§Examples
