Description

We have to implement Amount<T> as generic amount type.

  • durations
  • currencies
  • measurements (length, weight, volume, etc)
  • ... all other SI units
Amount<T> // generic amount type
Amount<meter> / Amount<kilometer>
Unit<kg> / Unit<g>

multiplication and division of units of different bases are allowed, other arithmetic operations only allowed on same base units. If same amount divided by same amount, result is decimal (unitless number)

Contributor guide

Research direction
Study Rust generics and unit type patterns. Implement the generic Amount<T> struct, then define unit types for durations, currencies, and SI measurements. Use trait bounds for arithmetic operations and ensure type safety.
