rustfm-scrobble is a Last.fm Scrobble API 2.0 crate for Rust. It allows easy acccess to the "scrobble" and "now playing" notification endpoints through a simple Rust API. It can be used to record song-plays from music players, build analog scrobbling tools similar to VinylScrobbler or work with IoT Devices. It was initially built to implement a Spotify scrobbling service using the Spotify Connect Protocol when the Alexa Spotify client did not support scrobbling plays to Last.fm.

• Scrobble songs to Last.fm ('scrobble' API endpoint)
• Publish now-playing song to Last.fm ('now playing' API endpoint)
• Batch scrobble support in Scrobbler::scrobble_batch and ScrobbleBatch
• Multiple authentication flows to gain permissions to publish to Last.fm user profile
  • Store a pre-authenticated session key & throw away secret data after initial authentication
• Simple error handling; each API operation returns a Result with a simple Error type on failure
• Unit tested

Add rustfm-scrobble to your Cargo.toml.
