### Initiate Aliyun OSS Bucket WORM Configuration (Rust)

Source: https://docs.rs/aliyun-oss-rs/0.3.0/src/aliyun_oss_rs/bucket/oss_bucket.rs_search=std%3A%3Avec

This function initiates a WORM (Write Once, Read Many) retention configuration for an Aliyun OSS bucket. It requires the `_async-base` feature. The function returns an `InitiateBucketWorm` object to start the WORM setup process.

```rust
/// Initiate WORM retention configuration.
///
/// 初始化 WORM 合规保留策略。
#[cfg(feature = "_async-base")]
pub fn initiate_bucket_worm(&self) -> InitiateBucketWorm {
    InitiateBucketWorm::new(self.oss.clone())
}
```

### Rust: Stream Object Download Example

An example demonstrating how to download an object from Alibaba Cloud OSS as a stream using `download_to_stream()` and process the chunks of data as they arrive. It utilizes `futures_util::StreamExt` for stream manipulation.

```rust
use futures_util::StreamExt;

let mut stream = object.get_object().download_to_stream().await.unwrap();
while let Some(item) = stream.next().await {
match item {
Ok(bytes) => {
// Do something with bytes...
}
Err(e) => eprintln!("Error: {}", e),
}
}
```

### Retrieve Bucket Website Configuration using Rust

Source: https://docs.rs/aliyun-oss-rs/0.3.0/src/aliyun_oss_rs/bucket/get_bucket_website.rs

This Rust code defines a struct `GetBucketWebsite` to retrieve the static website configuration of an Alibaba Cloud OSS bucket. It utilizes the `OssRequest` type and sends a GET request with the 'website' query parameter. The response is then parsed into a `WebsiteConfiguration` struct. Dependencies include `crate::{Error, common::body_to_bytes, error::normal_error, request::{Oss, OssRequest}}` and `http::Method`.

```rust
use crate::{
    Error,
    common::body_to_bytes,
    error::normal_error,
    request::{Oss, OssRequest},
};
use http::Method;

use super::WebsiteConfiguration;

/// Retrieve the static website configuration of a bucket.
///
/// See the [Alibaba Cloud documentation](https://help.aliyun.com/zh/oss/developer-reference/getbucketwebsite) for details.
///
/// 获取 Bucket 静态网站配置。
///
/// 详情参见 [阿里云文档](https://help.aliyun.com/zh/oss/developer-reference/getbucketwebsite)。
pub struct GetBucketWebsite {
    req: OssRequest,
}

impl GetBucketWebsite {
    pub(super) fn new(oss: Oss) -> Self {
        let mut req = OssRequest::new(oss, Method::GET);
        req.insert_query("website", "");
        GetBucketWebsite { req }
    }

    /// Send the request and return the parsed configuration.
    ///
    /// 发送请求并返回解析后的配置。
    pub async fn send(self) -> Result<WebsiteConfiguration, Error> {
        let response = self.req.send_to_oss()?.await?;
        match response.status() {
            code if code.is_success() => {
                let bytes = body_to_bytes(response.into_body()).await?;
                let config: WebsiteConfiguration =
                    serde_xml_rs::from_reader(bytes.as_ref()).map_err(|_| Error::OssInvalidResponse(Some(bytes)))?;
                Ok(config)
            }
            _ => Err(normal_error(response).await),
        }
    }
}
```

### Set Byte Range for GetObject Request in Rust

Source: https://docs.rs/aliyun-oss-rs/0.3.0/src/aliyun_oss_rs/object/get_object.rs

Configures the `GetObject` request to retrieve a specific byte range of an object. The `start` parameter specifies the beginning of the range (inclusive), and `end` (optional) specifies the end of the range (inclusive). Byte indexing starts at 0. Invalid ranges will result in the entire object being downloaded.

```Rust
pub fn set_range(mut self, start: usize, end: Option<usize>) -> Self {
        self.req.insert_header(
            "Range",
            format!("bytes={}-{}", start, end.map(|v| v.to_string()).unwrap_or_else(|| String::new())),
        );
        self
    }
```

### Quick Start: List Buckets (Async)

Source: https://docs.rs/aliyun-oss-rs/0.3.0/aliyun_oss_rs/index

Initializes an OssClient and lists buckets with a specified prefix using asynchronous operations. Requires a Tokio runtime. Replace placeholders with your actual AccessKeyId, AccessKeySecret, and region.

```rust
use aliyun_oss_rs::OssClient;

#[tokio::main] async fn main() {
    let mut client = OssClient::new("<AccessKeyId>", "<AccessKeySecret>", "cn-zhangjiakou");
    // Optional: internal/dualstack/custom endpoints
    // client.set_endpoint("oss-cn-zhangjiakou-internal.aliyuncs.com");

    let buckets = client.list_buckets().set_prefix("rust").send().await;
    println!("buckets = {:?}", buckets);
}
```

--------------------------------

### Build Pre-signed Object URL with AliCloud OSS

Source: https://docs.rs/aliyun-oss-rs/0.3.0/aliyun_oss_rs/object/struct.GetObjectUrl_search=Option%3CT%3E%2C+%28T+-%3E+U%29+-%3E+Option%3CU%3E

Demonstrates how to construct a pre-signed URL for an object in Alibaba Cloud OSS. This allows private objects to be downloaded directly via a signed URL. Refer to Alibaba Cloud documentation for more details.

```rust
impl GetObjectUrl {
    // ... other methods
    pub fn url(self, expires: OffsetDateTime) -> String {
        // Generate the signed URL with the given expiration time.
        // 使用给定的过期时间生成签名 URL。

### Rust: Set Byte Range for Object Retrieval

Source: https://docs.rs/aliyun-oss-rs/0.3.0/aliyun_oss_rs/object/struct.GetObject

Configures the byte range for an object retrieval operation using the `set_range` method on the `GetObject` struct. The `start` and `end` parameters define the byte range (inclusive start, exclusive end). Invalid values result in the entire object being downloaded. Byte indexing starts at 0.

```Rust
pub fn set_range(self, start: usize, end: Option<usize>) -> Self
```
