Via Environment

Set environment correctly:

export OPENDAL_FS_ROOT=/path/to/dir/

use std::sync::Arc;

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::Fs)?;

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

    Ok(())
}

Via Builder

use std::sync::Arc;

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

#[tokio::main]
async fn main() -> Result<()> {
    // Create fs backend builder.
    let mut builder = fs::Builder::default();
    // Set the root for fs, all operations will happen under this root.
    //
    // NOTE: the root must be absolute path.
    builder.root("/tmp");

    // `Accessor` provides the low level APIs, we will use `Operator` normally.
    let op: Operator = Operator::new(builder.build()?);

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

    Ok(())
}
