Environment

• OPENDAL_OBS_BUCKET required
• OPENDAL_OBS_ENDPOINT optional
• OPENDAL_OBS_ACCESS_KEY_ID optional
• OPENDAL_OBS_SECRET_ACCESS_KEY required

Example

Initiate via environment variables

Set environment correctly:

export OPENDAL_OBS_BUCKET=test
export OPENDAL_OBS_ROOT=/path/to/dir/
export OPENDAL_OBS_ACCESS_KEY_ID=access_key_id
export OPENDAL_OBS_SECRET_ACCESS_KEY=secret_access_key

use anyhow::Result;
use opendal::Object;
use opendal::Operator;
use opendal::Scheme;

#[tokio::main]
async fn main() -> Result<()> {
    let op: Operator = Operator::from_env(Scheme::Obs)?;

    // create an object handler to start operation on it.
    let _op: Object = op.object("test_file");

    Ok(())
}

Via Builder

use anyhow::Result;
use opendal::services::obs;
use opendal::Object;
use opendal::Operator;

#[tokio::main]
async fn main() -> Result<()> {
    // create backend builder
    let mut builder = obs::Builder::default();

    // set the storage bucket for OpenDAL
    builder.bucket("test");
    // Set the access_key_id and secret_access_key.
    //
    // OpenDAL will try load credential from the env.
    // If credential not set and no valid credential in env, OpenDAL will
    // send request without signing like anonymous user.
    builder.access_key_id("access_key_id");
    builder.secret_access_key("secret_access_key");

    let op: Operator = Operator::new(builder.build()?);

    // Create an object handle to start operation on object.
    let _: Object = op.object("test_file");

    Ok(())
}
