OpenDAL

Open Data Access Layer that connect the whole world together.

Status

OpenDAL is in alpha stage and has been early adopted by databend. Welcome any feedback at Discussions!

Quickstart

use anyhow::Result;
use futures::AsyncReadExt;

use opendal::services::fs;
use opendal::Operator;

#[tokio::main]
async fn main() -> Result<()> {
    let op = Operator::new(fs::Backend::build().root("/tmp").finish().await?);

    let o = op.object("test_file");

    // Write data info file;
    let w = o.new_writer();
    let n = w
        .write_bytes("Hello, World!".to_string().into_bytes())
        .await?;
    assert_eq!(n, 13);

    // Read data from file;
    let mut r = o.new_reader();
    let mut buf = vec![];
    let n = r.read_to_end(&mut buf).await?;
    assert_eq!(n, 13);
    assert_eq!(String::from_utf8_lossy(&buf), "Hello, World!");

    // Get file's Metadata
    let meta = o.stat().await?;
    assert_eq!(meta.content_length(), 13);

    // Delete file.
    o.delete().await?;

    Ok(())
}
