MusicBrainz rust is a utility crate for the the MusicBrainz API.


you may be looking for :

Usage

You can choose to use either the default async client or a blocking one.

async client:

musicbrainz_rs = "0.5.0"

blocking client:

musicbrainz_rs = { version = "0.5.0", features = ["blocking] }

Features

Note: All the example below use the blocking feature for the sake of conciseness.

Fetch query

To perform a lookups via fetch queries, you need to import the Fetch trait. This can be done using musicbrainz_rs::prelude

use musicbrainz_rs::entity::artist;
use musicbrainz_rs::entity::artist::*;
use musicbrainz_rs::prelude::*;

fn main() {
    let nirvana = Artist::fetch()
        .id("5b11f4ce-a62d-471e-81fc-a69a8278c7da")
        .execute();

    assert_eq!(nirvana.unwrap().name, "Nirvana".to_string());
}

Include parameters

You can also use includes to get more detail about a resource :

Every Musicbrainz resource has allowed include parameters.

use musicbrainz_rs::entity::label::*;
use musicbrainz_rs::prelude::*;

fn main() {
    let ninja_tune = Label::fetch()
        .id("dc940013-b8a8-4362-a465-291026c04b42")
        .with_tags()
        .with_ratings()
        .execute()
        .unwrap();

    assert!(ninja_tune
        .tags
        .unwrap()
        .iter()
        .any(|tag| tag.name == "independent"));

    assert!(ninja_tune.rating.is_some());
}

CoverArt query

Release and ReleaseGroup entities in MusicBrainz also allow you to make CoverArt queries on them:

use musicbrainz_rs::entity::release::*;
use musicbrainz_rs::entity::CoverartResponse;
use musicbrainz_rs::prelude::*;
use musicbrainz_rs::FetchCoverart;

fn main() {
    // CoverArt Query for a Release.
    let in_utero_coverart = Release::fetch_coverart()
        .id("76df3287-6cda-33eb-8e9a-044b5e15ffdd")
        .execute()
        .expect("Unable to get cover art");

    if let CoverartResponse::Json(coverart) = in_utero_coverart {
        assert!(!coverart.images[0].back);
        assert_eq!(
            coverart.images[0].image,
            "http://coverartarchive.org/release/76df3287-6cda-33eb-8e9a-044b5e15ffdd/829521842.jpg"
        );
    } else {
        assert!(false);
    }

    let in_utero = Release::fetch()
        .id("76df3287-6cda-33eb-8e9a-044b5e15ffdd")
        .execute()
        .expect("Unable to get release");

    // Calling `get_coverart()` method on an already fetched Release entity.
    let in_utero_coverart = in_utero
        .get_coverart()
        .execute()
        .expect("Unable to get coverart");

    if let CoverartResponse::Json(coverart) = in_utero_coverart {
        assert!(!coverart.images[0].back);
        assert_eq!(
            coverart.images[0].image,
            "http://coverartarchive.org/release/76df3287-6cda-33eb-8e9a-044b5e15ffdd/829521842.jpg"
        );
    } else {
        assert!(false);
    }

    // CoverArt Query Builder to fetch a specific resource.
    let in_utero_500px_front_coverart = Release::fetch_coverart()
        .id("76df3287-6cda-33eb-8e9a-044b5e15ffdd")
        .res_500()
        .back()
        .execute()
        .expect("Unable to get cover art");

    if let CoverartResponse::Url(coverart_url) = in_utero_500px_front_coverart {
        println!("{}", coverart_url);
    } else {
        assert!(false);
    }
}

Browse query

Use musicbrainz_rs::Browse or bring it in scope using musicbrainz_rs::prelude to perform a browse query. Just like Include every muscibrainz resource has allowable linked entities for such queries.

use musicbrainz_rs::entity::artist;
use musicbrainz_rs::entity::artist::Artist;
use musicbrainz_rs::prelude::*;

fn main() {
    let artists_on_in_utero_release = Artist::browse()
        .by_release("18d4e9b4-9247-4b44-914a-8ddec3502103")
        .execute();

    let artists_on_in_utero_release = artists_on_in_utero_release.unwrap();

    artists_on_in_utero_release
        .entities
        .iter()
        .for_each(|artist| println!("{:?}", artist.name));
}

Search query

Use musicbrainz_rs::Search to perform a search query.

use musicbrainz_rs::entity::artist::Artist;
use musicbrainz_rs::prelude::*;

fn main() {
    musicbrainz_rs::config::set_user_agent("my_awesome_app/1.0");

    let query = Artist::query_builder()
        .artist("Miles Davis")
        .and()
        .country("US")
        .build();

    let query_result = Artist::search(query).execute().unwrap();
    let query_result: Vec<String> = query_result.entities
        .iter()
        .map(|artist| artist.name.clone()).collect();

    assert!(query_result.contains(&"Miles Davis".to_string()));
    assert!(query_result.contains(&"Miles Davis Quintet".to_string()));
}

Custom user agent

You can set your application user-agent as recommended in the musicbrainz documentation :

use musicbrainz_rs::entity::artist::Artist;
use musicbrainz_rs::prelude::*;

fn main() {
    musicbrainz_rs::config::set_user_agent("my_awesome_app/1.0");

    let nirvana = Artist::fetch()
        .id("5b11f4ce-a62d-471e-81fc-a69a8278c7da")
        .execute();

    assert_eq!(nirvana.unwrap().name, "Nirvana".to_string());
}
