The Dark Sky Rust SDK by Jesse Grillo allows developers to integrate weather foresting applications. The SDK communicates with the Dark Sky API, formerly Forecast.io API. Its documentation provides the Crates.io access link to a crate. The SDK is currently a beta release that is subject to changes in the future.
HERE Technologies is at CES 2020 and is showcasing two APIs. Its Public Transit API helps improve the public transportation experience by providing real-time information from departure boards and other public data. The Intermodal Routing API creates a smart routing experience across cities.
