# storage

S3-compatible object storage client for models, datasets, and training artifacts.

## Key Types

- `S3Client` — upload, download, and manage S3 objects
- `S3Config` — bucket, region, and credential configuration
- Local caching layer for frequently accessed models
- Checksum verification (MD5, SHA256) on upload/download

## Features

- Model versioning and artifact management
- Compression/decompression (gzip, zstd)
- High-level file management API (list, delete, prefix operations)

## Usage

```rust
use storage::{S3Client, S3Config};
let client = S3Client::new(config)?;
client.upload_file(&path, "models/v1/model.bin", true)?;
```
