Quickstart

use opendal::Result;
use opendal::layers::LoggingLayer;
use opendal::services;
use opendal::Operator;

#[tokio::main]
async fn main() -> Result<()> {
    // Pick a builder and configure it.
    let mut builder = services::S3::default();
    builder.bucket("test");

    // Init an operator
    let op = Operator::new(builder)?
        // Init with logging layer enabled.
        .layer(LoggingLayer::default())
        .finish();

    // Write data
    op.write("hello.txt", "Hello, World!").await?;

    // Read data
    let bs = op.read("hello.txt").await?;

    // Fetch metadata
    let meta = op.stat("hello.txt").await?;
    let mode = meta.mode();
    let length = meta.content_length();

    // Delete
    op.delete("hello.txt").await?;

    Ok(())
}

Branding

The first and most prominent mentions must use the full form: Apache OpenDAL™ of the name for any individual usage (webpage, handout, slides, etc.) Depending on the context and writing style, you should use the full form of the name sufficiently often to ensure that readers clearly understand the association of both the OpenDAL project and the OpenDAL software product to the ASF as the parent organization.
