The sun
crate is a library for calculating the position of the sun and sun phases
(like sunrise, sunset).
It is a port of the JavaScript
library
suncalc.
§Example
let unixtime = 1_362_441_600_000;
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}");
// calculate time of sunrise
let time_ms = sun::time_at_phase(unixtime, sun::SunPhase::Sunrise, lat, lon, 0.0);
assert_eq!(time_ms, 1_362_463_116_241);
Structs§
Enums§
- SunPhase
- Sun phases for use with
time_at_phase
.
Functions§
- pos
- Calculates the sun position for a given date and latitude/longitude. The angles are calculated as radians.
- time_
at_ phase - Calculates the time for the given
SunPhase
at a given date, height and Latitude/Longitude. The returned time is the unix time in milliseconds.
