Quickstart

use anyhow::Result;
use futures::AsyncReadExt;
use futures::StreamExt;
use opendal::services::fs;
use opendal::ObjectMode;
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.writer();
    let n = w
        .write_bytes("Hello, World!".to_string().into_bytes())
        .await?;

    // Read data from file;
    let mut r = o.reader();
    let mut buf = vec![];
    let n = r.read_to_end(&mut buf).await?;

    // Read range from file;
    let mut r = o.range_reader(10, 1);
    let mut buf = vec![];
    let n = r.read_to_end(&mut buf).await?;

    // Get file's Metadata
    let meta = o.metadata().await?;

    // List current dir.
    let mut obs = op.objects("").map(|o| o.expect("list object"));
    while let Some(o) = obs.next().await {
        let meta = o.metadata().await?;
        let path = meta.path();
        let mode = meta.mode();
        let length = meta.content_length();
    }

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

    Ok(())
