A Rust library for calculating sun positions
A rust port of the JS library suncalc.
Add the following to your Cargo.toml
[dependencies]
sun = "0.2"
pub fn main() {
let unixtime = 1362441600000;
let lat = 48.0;
let lon = 9.0;
let pos = sun::pos(unixtime,lat,lon);
let az = pos.azimuth.to_degrees();
let alt = pos.altitude.to_degrees();
println!("The position of the sun is {}/{}", az, alt);
let time_ms = sun::time_at_phase(unixtime, sun::SunPhase::Sunrise, lat, lon, 0.0);
println!("Sunrise is at {}", time_ms);
}
Hi!
Thank you for your crate! Nice to have this kind of calculations in rust! :)
I am now putting it into my project :)
I want to ask about one thing:
I think it is unable that unixtime_in_ms could be negative, what do you think?
In this case it would be probably better if you change it from i64 to u128.
And u128 is because the rust's Duration::as_millis() is returning u128 type.
So in this case we don't need to cast...
Look how I am obtaining the time:

Hello! I was looking into porting the moon functions from mourner/suncalc. Would you want those in this repo?
I've done the moon position function so far, and I noticed to you add PI to the azimuth in the rust version. Just curious why; I don't know anything about astronomy math :)
