Struct FutureValue 

pub struct FutureValue { /* private fields */ }

Compute the future value

Parameters

• rate : an interest rate compounded once per period
• nper : number of compounding periods
• pmt : payment in each period
• pv : present value
• when : when payments are due WhenType. Defaults to When::End

Return:

• fv: the value at the end of the nper periods, which is used in other modules as parameter

Example

use rfinancial::*;
let fv = FutureValue::from_tuple((0.075, 20, -2000.0, 0.0, WhenType::End));
println!("{:#?}'s fv is {:?}", fv, fv.get());

Implementations

impl FutureValue

pub fn from_tuple(tup: (f64, u32, f64, f64, WhenType)) -> Self

Instantiate a FutureValue instance from a tuple of (rate, nper, pmt, pv and when) in said order

pub fn from_map(map: ParaMap) -> Result<Self>

Instantiate a FutureValue instance from a hash map with keys of (rate, nper, pmt, pv and when) in said order Since [HashMap] requires values of same type, we need to wrap into a variant of enum

pub fn get(&self) -> Result<f64>

Get the future value from an instance of FutureValue

Trait Implementations

impl Debug for FutureValue

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

Formats the value using the given formatter.
