Crate s3_sync

Expand description

High level synchronous S3 client.

This client wraps Rusoto S3 and provides the following features:

check if bucket or object exists,
list objects that match prefix as iterator that handles pagination transparently,
put large objects via multipart API and follow progress via callback,
delete single or any number of objects via bulk delete API,
deffer execution using ensure crate for putting and deleting objects.

Example usage

use s3_sync::{S3, Region, ObjectBodyMeta, BucketKey, Bucket};
use std::io::Cursor;
use std::io::Read;

let test_bucket = std::env::var("S3_TEST_BUCKET").expect("S3_TEST_BUCKET not set");
let test_key = "foobar.test";

let s3 = S3::default();

let bucket = s3.check_bucket_exists(Bucket::from_name(test_bucket)).expect("check if bucket exists")
    .left().expect("existing bucket");
let bucket_key = BucketKey::from_key(&bucket, test_key);

let body = Cursor::new(b"hello world".to_vec());
let object = s3.put_object(bucket_key, body, ObjectBodyMeta::default()).unwrap();

let mut body = Vec::new();
s3.get_body(&object).expect("object body").read_to_end(&mut body).unwrap();

assert_eq!(&body, b"hello world");
