Storage Integration Documentation
📦 SDK Notice: The code examples in this document represent the planned SDK interface design. The SELF SDK is currently under development and these APIs are subject to change.
Overview
The SELF SDK provides seamless integration with the SELF storage layer, including IPFS and OrbitDB. This documentation covers the available storage operations and their usage.
IPFS Integration
Key Features
- File upload and retrieval
- Content addressing
- Decentralized storage
- Version control
Usage Example
// Upload file to IPFS
let ipfs = IPFSIntegration::new();
let cid = ipfs.upload_file("path/to/file.txt").unwrap();
// Retrieve file
let content = ipfs.get_file(&cid).unwrap();
OrbitDB Integration
Key Features
- Decentralized database access
- Real-time synchronization
- Event logging
- Version control
Usage Example
// Create OrbitDB store
let orbitdb = OrbitDBIntegration::new("validator_store");
// Add validator data
let validator_data = ValidatorData {
validator_id: "validator_1",
reputation: 100,
last_update: Utc::now(),
};
orbitdb.add_validator(&validator_data).unwrap();
// Query validator data
let validators = orbitdb.get_validators().unwrap();
Cross-Chain Storage
Key Features
- Cross-chain file sharing
- Consistent storage across chains
- Version synchronization
- Data integrity verification
Usage Example
// Share file across chains
let cross_chain = CrossChainStorage::new();
let shared_cid = cross_chain.share_file("source_chain", "target_chain", "file_cid").unwrap();
// Verify cross-chain data
let verified = cross_chain.verify_data("source_chain", "target_chain", &shared_cid).unwrap();
Best Practices
Security
- Encrypt sensitive data
- Use proper authentication
- Implement access control
- Monitor storage usage
Performance
- Batch operations when possible
- Use proper caching
- Implement retry mechanisms
- Monitor network latency
Error Handling
Common Errors
- Storage limit exceeded
- Invalid file format
- Network errors
- Permission denied
Error Handling Example
match ipfs.upload_file("path/to/file.txt") {
Ok(cid) => println!("File uploaded successfully: {}", cid),
Err(e) => match e {
IPFSError::StorageLimitExceeded => println!("Storage limit exceeded"),
IPFSError::InvalidFileFormat => println!("Invalid file format"),
IPFSError::NetworkError => println!("Network error occurred"),
_ => println!("Unknown error: {}", e),
}
}
