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
    .expect("failed to upload files");

//profit
println!("upload results: {:#?}", upload_results);
