MusicBrainz rust is a utility crate for the the MusicBrainz API.
you may be looking for :
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] }Note: All the example below use the blocking feature for the sake of conciseness.
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());
}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());
}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);
}
}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));
}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()));
}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());
}To see what is currently implemented in the crate you can look at the tests directory.
You can run examples with cargo run --example example_name
