Intro

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

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.

Features

sync and async features are enabled by default. In case you require a different set of features you are probably better off passing in default-features = false, see below. Both sync and async use native-tls as their TLS backend, there are rustls-tls alternative backends available for both of them. rustls-tls features are functionally compatible to their native-tls counterparts, and can be toggled individually or together with the rustls feature. wasm feature is sugar for [sync-rustls]. Useful feature combinations are listed at the bottom of this doc.

Presign

feature
sync, wasm presign_put
sync, wasm presign_get

GET

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

feature
async get_object
async get_object_stream
sync, wasm get_object_blocking
sync, wasm get_object_stream_blocking
async tokio_get_object_stream

PUT

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

features
async put_object
async put_object_stream
sync, wasm put_object_blocking
sync, wasm put_object_stream_blocking
async tokio_put_object_stream

List

features
async list
sync, wasm list_blocking

DELETE

features
async delete_object
sync, wasm delete_object_blocking

Location

features
async location
sync, wasm location_blocking

Tagging

features
async put_object_tagging
sync, wasm put_object_tagging_blocking
async get_object_tagging
sync, wasm get_object_tagging_blocking

Usage (in Cargo.toml)

[dependencies]
rust-s3 = "0.23"

Features

Disable SSL verification for endpoints, useful for custom regions
# Only available for `async` feature, as `rustls-tls` does not support dangereous features ATM
[dependencies]
rust-s3 = {version = "0.23", features = ["async", "no-verify-ssl"], default-features = false}
Fail on HTTP error responses
[dependencies]
rust-s3 = {version = "0.23", features = ["fail-on-err"]}
Different SSL backends

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

[dependencies]
rust-s3 = {version = "0.23", features = ["rustls"], default-features = false}
WASM
[dependencies]
rust-s3 = {version = "0.23", features = ["wasm"], default-features = false}
