Note: This repository is a fork of rust-s3 but with a lot of simplifications like only tokio support with async, no blocking implementations, and next to zero macro usage. The only reason this fork exists is because the macro expansions are fairly inaccurate and make development frustrating for me. Plus, its pretty common to use async code when consuming an S3 API, so I don't feel the need of carrying all the "mutual exclusive macro" dead weights around for every minor feature.

rust-s3-async docs

Rust library for working with Amazon S3 or arbitrary S3 compatible APIs, fully compatible with async/await and futures ^0.3.

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, as 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.

Quick Start

Read and run examples from the examples folder, make sure you have valid credentials for the variant you're running.

# tokio, default
cargo run --example tokio

# minio
# First, start Minio on port 9000.
AWS_ACCESS_KEY_ID="minioadmin" \
AWS_SECRET_ACCESS_KEY="minioadmin" \
    cargo run --example minio

# r2
cargo run --example r2

# google cloud
cargo run --example google-cloud

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
• fail-on-err - panic on any error
• no-verify-ssl - disable SSL verification for endpoints, useful for custom regions

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
list	async
exists	async

Presign

POST	presign_put
PUT	presign_put
GET	presign_get
DELETE	presign_delete

GET

There are a few different options for getting an object and methods are generic over tokio::io::AsyncWriteExt.

async/sync/async-blocking	get_object
async/sync/async-blocking	get_object_stream
async/sync/async-blocking	get_object_to_writer

PUT

Each GET method has a PUT companion, and 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
