Positive

A type-safe wrapper for guaranteed positive decimal values.

This crate provides the Positive type, which encapsulates a Decimal value and ensures through its API that the contained value is always positive (greater than or equal to zero).

Features

• Type Safety: Compile-time guarantees that values are non-negative
• Decimal Precision: Built on rust_decimal for accurate financial calculations
• Rich API: Comprehensive arithmetic operations, conversions, and utilities
• Serde Support: Full serialization/deserialization support

Example

use positive::{Positive, pos};

let price = pos!(100.50);
let quantity = Positive::new(10.0).unwrap();
let total = price * quantity;
