//! - Documentation: All docs are carried byself, visit [`docs`] for more.

//! # Quick Start
//!
//! ```no_run
//! use opendal::layers::LoggingLayer;
//! use opendal::services;
//! use opendal::Operator;
//! use opendal::Result;
//!
//! #[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(())
//! }
