Rust library for cloud storage across major cloud providers It aims to provide simple to use functions to perform CRUD operations on buckets and blobs. Waihona simply means storage in Hawaiian
The following feature flags exist for this crate
-
aws
: Enable aws provider and dependencies - []
gcp
: Enable gcp provider and dependencies - []
azure
: Enable azure provider and dependencies
These quick examples will show you how to make use of the library for basic actions
List buckets from project waihona on GCP
// ensure to export service credential using GOOGLE_APPLICATION_CREDENTIALS
#[cfg(feature = "gcp")]
use waihona::providers::gcp::GcpBucket;
#[tokio::test]
#[cfg(feature = "gcp")]
async fn test_list_buckets() -> Vec<GcpBucket> {
// Import Buckets trait from crate
use waihona::types::bucket::{Buckets};
use waihona::providers::gcp;
let mut gcp_buckets = providers::gcp::GcpBuckets::new(
"waihona"
);
// Returns (Vec<GcpBucket, Option<String>)
// where Option<String> is the cursor for the token for next page listing
let resp = gcp_buckets.list().await;
resp[0]
}
Check bucket waihona exists on AWS
#[tokio::test]
#[cfg(feature = "aws")]
async fn test_bucket_exists() -> bool {
use waihona::types::bucket::{Buckets};
use waihona::providers;
let mut aws_buckets = providers::aws::AwsBuckets::new(
"us-east-2"
);
let resp = aws_buckets.exists(
String::from("waihona")
).await;
resp
}
Write content to a blob "example.txt" in waihona bucket on Azure
#[cfg(feature = "azure")]
use waihona::providers::azure::AzureBlob;
#[tokio::test]
#[cfg(feature = "azure")]
async fn test_create_blob() -> AzureBlob {
// !! UNIMPLEMENTED
use waihona::types::bucket::{Buckets, Bucket};
use waihona::types::blob::{Blob};
use waihona::providers;
use bytes::Bytes;
let mut azure_buckets = providers::azure::AzureBuckets::new();
let waihona = azure_buckets.open(
String::from("waihona"),
).await.unwrap();
let mut blob = waihona.write_blob(
"example.txt".to_owned(),
Some(Bytes::from("Hello world"))
).await
.unwrap();
blob
}
Copy file content from "example.txt" blob on AWS to blob on GCP and delete AWS blob afterwards assuming waihona buckets exist on both platforms
use waihona::providers::gcp::GcpBlob;
#[tokio::test]
#[cfg(all(feature = "gcp", feature = "aws" ))]
async fn test_transfer_blob() -> GcpBlob {
use waihona::types::bucket::{Buckets, Bucket};
use waihona::types::blob::{Blob};
use waihona::providers;
use bytes::Bytes;
let mut gcp_buckets = providers::gcp::GcpBuckets::new(
"gcp-project-name"
);
let gcp_waihona = gcp_buckets.open(
String::from("waihona"),
).await.unwrap();
let mut aws_blob = providers::aws::AwsBlob::get(
"us-east-2", // Region
"waihona", // Bucket name
"example.txt", // Blob name
None // Content range
).await
.unwrap();
let content: Bytes = aws_blob.read().unwrap();
let gcp_blob = waihona.write_blob(
"example.txt".to_owned(),
Some(content)
).await
.unwrap();
aws_blob.delete().unwrap();
gcp_blob
}
