Intro

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.

Buckets

create	async
delete	async

Presign

PUT	presign_put
GET	presign_get

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

PUT

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

List

async	list

DELETE

async	delete_object

Location

async	location

Tagging

async	put_object_tagging
async	get_object_tagging

Head

async	head_object

Usage (in Cargo.toml)

[dependencies]
rust-s3 = "0.27"

Features

Disable SSL verification for endpoints, useful for custom regions

[dependencies]
rust-s3 = {version = "0.26.0", features = ["no-verify-ssl"]}

Fail on HTTP error responses

[dependencies]
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

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

Use async-std instead of tokio

By default the with-tokio feature is enabled. To switch to async-std you need to disable the default features and specify the with-async-std feature

[dependencies]
rust-s3 = {version = "0.27.0-beta8", features = ["with-async-std"], default-features = false}
