qtty

Why it exists

qtty provides dimensional quantities (Length, Angle, Mass, Time, Velocity, etc.) with operator overloading and compile-time unit checking. Powers Siderust's physical computations.

Key Features

• Compile-time dimensional analysis
• Zero-cost abstractions
• SI and astronomical units
• No-std compatible

Getting Started

# Add to your Cargo.toml
[dependencies]
qtty = "0.1"

# Use physical quantities
use qtty::{AU, KM, DAY};

let distance = 1.523 * AU;  // Mars semi-major axis
let period = 686.97 * DAY;
let speed = distance / period;  // Compiler validates dimensions
