Modest interface towards Amazon S3, as well as S3 compatible object storage APIs such as Wasabi, Yandex, Minio or Google Cloud Storage. Supports: put, get, list, delete, operations on tags and location, well as head.

Additionally a dedicated presign_get Bucket method is available. This means you can upload to s3, and give the link to select people without having to worry about publicly accessible files on S3. This also means that you can give people a PUT presigned URL, meaning they can upload to a specific key in S3 for the duration of the presigned URL.

AWS, Yandex and Custom (Minio) Example

Path or subdomain style URLs and headers

Bucket struct provides constructors for path-style paths, subdomain style is the default. Bucket exposes methods for configuring and accessing path-style configuration.


create async
delete async


PUT presign_put
GET presign_get


There are a few different options for getting an object. sync and async methods are generic over std::io::Write, while tokio methods are generic over tokio::io::AsyncWriteExt.

async get_object
async get_object_stream


Each GET method has a PUT companion sync and async methods are generic over std::io::Read. async stream methods are generic over futures::io::AsyncReadExt, while tokio methods are generic over tokio::io::AsyncReadExt.

async put_object
async put_object_with_content_type
async put_object_stream


async list


async delete_object


async location


async put_object_tagging
async get_object_tagging


async head_object

Usage (in Cargo.toml)

rust-s3 = "0.27"


Disable SSL verification for endpoints, useful for custom regions
rust-s3 = {version = "0.26.0", features = ["no-verify-ssl"]}
Fail on HTTP error responses
rust-s3 = {version = "0.26.0", features = ["fail-on-err"]}
Different SSL backends

Default is reqwest/native-tls, it is possible to switch to reqwest/rustls-tls which is more portable

rust-s3 = {version = "0.26.0", features = ["rustls-tls"]}
