Examples

opendal_store_opendal depends on the opendal crate. Please make sure to always use the latest versions of both.

latest opendal

1. using object_store API to access S3

Add the following dependencies to your Cargo.toml with correct version:

[dependencies]
object_store = "0.14.1"
object_store_opendal =  "xxx"   # see the latest version above
opendal = { version = "xxx", features = ["services-s3"] }  # see the latest version above

Build OpendalStore via opendal::Operator:

use std::sync::Arc;

use bytes::Bytes;
use object_store::path::Path;
use object_store::ObjectStoreExt;
use object_store_opendal::OpendalStore;
use opendal::services::S3;
use opendal::{Builder, Operator};

#[tokio::main]
async fn main() {
    let builder = S3::from_map(
        vec![
            ("access_key".to_string(), "my_access_key".to_string()),
            ("secret_key".to_string(), "my_secret_key".to_string()),
            ("endpoint".to_string(), "my_endpoint".to_string()),
            ("region".to_string(), "my_region".to_string()),
        ]
        .into_iter()
        .collect(),
    ).unwrap();

    // Create a new operator
    let operator = Operator::new(builder).unwrap();

    // Create a new object store
    let object_store = Arc::new(OpendalStore::new(operator));

    let path = Path::from("data/nested/test.txt");
    let bytes = Bytes::from_static(b"hello, world! I am nested.");

    object_store.put(&path, bytes.clone().into()).await.unwrap();

    let content = object_store
        .get(&path)
        .await
        .unwrap()
        .bytes()
        .await
        .unwrap();

    assert_eq!(content, bytes);
}

WASM support

To build with wasm32-unknown-unknown target, you need to enable the send_wrapper feature:

cargo build --target wasm32-unknown-unknown --features send_wrapper

Branding

The first and most prominent mentions must use the full form: Apache OpenDAL™ of the name for any individual usage (webpage, handout, slides, etc.) Depending on the context and writing style, you should use the full form of the name sufficiently often to ensure that readers clearly understand the association of both the OpenDAL project and the OpenDAL software product to the ASF as the parent organization.
