weatherman-core

Framework-free weather logic shared by the weatherman Iced GUI and the weatherman-tui Ratatui TUI — and usable on its own as a drop-in weather API provider library.

No GUI or TUI dependencies. Data comes from Open-Meteo (no API key required) with geocoding via Nominatim/OpenStreetMap.

Features

• Domain models: WeatherCondition, Location, CurrentWeather, HourlyForecast, DailyForecast, Forecast
• WeatherProvider trait so you can swap the backend (paid API, cache, test double…)
• WeatherForecaster — Open-Meteo implementation of WeatherProvider
• LocationService — IP-based and name-based geocoding
• UI-agnostic formatting helpers (units, wind direction, condition tones, local time)

Example

use weatherman_core::{LocationService, WeatherForecaster, WeatherProvider, WeatherConfig};

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let location = LocationService::new().get_location_by_name("Berlin").await?;
    let provider = WeatherForecaster::new(WeatherConfig::default());
    let forecast = provider.forecast(&location).await?;
    println!("{} hourly, {} daily", forecast.hourly.len(), forecast.daily.len());
    Ok(())
}
