Example - Upload Multiple Files to ShdwDrive Using Rust
This Rust code example demonstrates how to upload multiple files to a ShdwDrive using the shadow_drive_rust library. It initializes a tracing subscriber, reads a keypair from a file, creates a ShdwDrive client, derives the storage account public key, reads files from a directory, creates a vector of ShadowFile structs for upload, and finally uploads the files to the ShdwDrive.
// Example - Upload Multiple Files to ShdwDrive Using Rust
// Initialize the tracing.rs subscriber with environment filter
tracing_subscriber::fmt()
.with_env_filter("off,shadow_drive_rust=debug")
.init();
// Load keypair from file using the provided KEYPAIR_PATH
let keypair = read_keypair_file(KEYPAIR_PATH).expect("failed to load keypair at path");
// Create a new ShdwDriveClient instance with the loaded keypair and server URL
let shdw_drive_client = ShadowDriveClient::new(keypair, "https://ssc-dao.genesysgo.net");
// Derive the storage account public key using the keypair's public key
let pubkey = keypair.pubkey();
let (storage_account_key, _) =
shadow_drive_rust::derived_addresses::storage_account(&pubkey, 0);
// Read files from the "multiple_uploads" directory
let dir = tokio::fs::read_dir("multiple_uploads")
.await
.expect("failed to read multiple uploads dir");
// Create a Vec of ShadowFile structs for upload
// by iterating through the directory entries
let mut files = tokio_stream::wrappers::ReadDirStream::new(dir)
.filter(Result::is_ok)
.and_then(|entry| async move {
Ok(ShadowFile::file(
entry
.file_name()
.into_string()
.expect("failed to convert os string to regular string"),
entry.path(),
))
})
.collect::<Result<Vec<_>, _>>()
.await
.expect("failed to create shdw files for dir");
// Add a ShadowFile with bytes content to the files vector
files.push(ShadowFile::bytes(
String::from("buf.txt"),
&b"this is a buf test"[..],
));
// Upload the files to the ShdwDrive using the storage_account_key
let upload_results = shdw_drive_client
.upload_multiple_files(&storage_account_key, files)
.await

//profit

Methods
add_immutable_storage
Definition
Adds storage capacity to the specified immutable StorageAccount. This will fail if the StorageAccount is not immutable.
Parameters
storage_account_key - The public key of the immutable StorageAccount.
size - The additional amount of storage you want to add. E.g if you have an existing StorageAccount with 1MB of storage but you need 2MB total, size should equal 1MB. When specifying size, only KB, MB, and GB storage units are currently supported.
Example of add_immutable_storage
let add_immutable_storage_response = shdw_drive_client
.add_immutable_storage(storage_account_key, Byte::from_str("1MB").expect("invalid byte string"))
.await?;
Adds storage capacity to the specified StorageAccount.
Parameters
storage_account_key - The public key of the StorageAccount.
size - The additional amount of storage you want to add. E.g if you have an existing StorageAccount with 1MB of storage but you need 2MB total, size should equal 1MB. When specifying size, only KB, MB, and GB storage units are currently supported.
Example of add_storage

Parameters
storage_account_key - The public key of the StorageAccount that you want to unmark for deletion.
Example of cancel_delete_storage_account
let cancel_delete_storage_account_response = shdw_drive_client

This method is used to update your storage account's stake amount. It is required to call this method after calling the `` method in order for your stage account to update properly.
This method is used to top up a storage account's $SHDW balance to cover any necessary fees, like mutable storage fees which are collected every epoch. It is necessary to call the `` method after this.
