rust-s3 [docs]

Rust library for working with Amazon S3 or arbitrary S3 compatible APIs, fully compatible with async/await and futures ^0.3. All async features can be turned off and sync only implementations can be used.

Intro

Modest interface towards Amazon S3, as well as S3 compatible object storage APIs such as Backblaze B2, 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.

Features

There are a lot of various features that enable a wide variety of use cases, refer to s3/Cargo.toml for an exhaustive list. Below is a table of various useful features as well as a short description for each.

• default - tokio runtime and a native-tls implementation
• blocking - generates *_blocking variant of all Bucket methods, otherwise only async versions are available
• fail-on-err - panic on any error
• no-verify-ssl - disable SSL verification for endpoints, useful for custom regions
• never-encode-slash - never encode slashes in paths

With default-features = false

• with-async-std - async-std runtime
• sync - no async runtime, attohttpc is used for HTTP requests
• tags - required for Bucket::get_object_tagging

All runtimes support either native-tls or rustls-tls, there are features for all combinations, refer to s3/Cargo.toml for a complete list.

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. blocking feature will generate a *_blocking variant of all of the methods listed below.

Buckets

create	async
delete	async

Presign

PUT	presign_put
GET	presign_get
DELETE	presign_delete

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/sync/async-blocking	get_object
async/sync/async-blocking	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/sync/async-blocking	put_object
async/sync/async-blocking	put_object_with_content_type
async/sync/async-blocking	put_object_stream

List

async/sync/async-blocking	list

DELETE

async/sync/async-blocking	delete_object

Location

async/sync/async-blocking	location

Tagging

async/sync/async-blocking	put_object_tagging
async/sync/async-blocking	get_object_tagging

Head

async/sync/async-blocking	head_object
