MinIO Rust SDK for Amazon S3 Compatible Cloud Storage

The MinIO Rust SDK is a Simple Storage Service (aka S3) client for performing bucket and object operations to any Amazon S3 compatible object storage service. It provides a strongly-typed, async-first interface to the MinIO and Amazon S3-compatible object storage APIs.

Each supported S3 operation has a corresponding request builder (for example: [BucketExists], [PutObject], [UploadPartCopy]), which allows users to configure request parameters using a fluent builder pattern.

All request builders implement the [S3Api] trait, which provides the async send method to execute the request and return a typed response.

Basic Usage

use minio::s3::MinioClient;
use minio::s3::creds::StaticProvider;
use minio::s3::http::BaseUrl;
use minio::s3::types::S3Api;
use minio::s3::response::BucketExistsResponse;

#[tokio::main]
async fn main() {
    let base_url = "play.min.io".parse::<BaseUrl>().unwrap();
    let static_provider = StaticProvider::new("Q3AM3UQ867SPQQA43P2F", "zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG", None);
    let client = MinioClient::new(base_url, Some(static_provider), None, None).unwrap();

    let exists: BucketExistsResponse = client
        .bucket_exists("my-bucket")
        .send()
        .await
        .expect("request failed");

    println!("Bucket exists: {}", exists.exists);
}

Features

• Request builder pattern for ergonomic API usage
• Full async/await support via [tokio]
• Strongly-typed responses
• Transparent error handling via Result<T, Error>

Design

• Each API method on the [MinioClient] returns a builder struct
• Builders implement [ToS3Request] for request conversion and [S3Api] for execution
• Responses implement [FromS3Response] for consistent deserialization
