Examples

Via Builder

use std::sync::Arc;

use anyhow::Result;
use opendal::services::Dbfs;
use opendal::Operator;

#[tokio::main]
async fn main() -> Result<()> {
    let mut builder = Dbfs::default()
        // set the root for Dbfs, all operations will happen under this root
        //
        // Note:
        // if the root is not exists, the builder will automatically create the
        // root directory for you
        // if the root exists and is a directory, the builder will continue working
        // if the root exists and is a folder, the builder will fail on building backend
        .root("/path/to/dir")
        // set the endpoint of Dbfs workspace
        .endpoint("https://adb-1234567890123456.78.azuredatabricks.net")
        // set the personal access token for builder
        .token("access_token");

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

    Ok(())
}
