Platform-Specific Details

WebAssembly (WASM)

Fully Implemented Features:

IndexedDB storage with automatic fallback to LocalStorage
Web Worker support for background operations
Compression using browser-native APIs
Memory cache with LRU eviction
Browser performance profiling
Network access through fetch API

Configuration:

use synaptic::cross_platform::wasm::{WasmAdapter, WasmConfig};

let config = WasmConfig {
    db_name: "my_app_memory".to_string(),
    enable_compression: true,
    enable_web_worker: true,
    enable_memory_cache: true,
    max_cache_size: 50 * 1024 * 1024, // 50MB
    worker_timeout_seconds: 30,
    ..Default::default()
};

let adapter = WasmAdapter::new_with_config(config)?;

Limitations:

No file system access (browser security)
Limited memory allocation (browser constraints)
No multi-threading (single-threaded JavaScript)
Background processing limited to Web Workers

Dependencies:

[dependencies]
synaptic = { version = "0.1", features = ["wasm", "compression"] }

iOS Platform

Fully Implemented Features:

Core Data integration for persistent storage
iOS-specific memory pressure handling
Background app refresh support
Battery optimization with iOS power management
Keychain integration for secure storage
Native performance profiling

Configuration:

use synaptic::cross_platform::mobile::{iOSAdapter, MobileConfig};

let config = MobileConfig {
    enable_battery_optimization: true,
    enable_background_sync: true,
    memory_pressure_threshold: 0.8,
    cache_size_limit: 100 * 1024 * 1024, // 100MB
    enable_compression: true,
    ..Default::default()
};

let adapter = iOSAdapter::new_with_config(config)?;

Platform Integration:

Swift bridge for Core Data operations
iOS memory pressure notifications
Background app refresh handling
iOS-specific file system paths

Limitations:

Memory constraints (iOS kills memory-heavy apps)
Background processing limitations
App Store review requirements for data usage

Android Platform

Fully Implemented Features:

SQLite/Room database integration
Android-specific memory management
Doze mode and app standby handling
JNI integration for native operations
Android keystore for secure storage
Background service support

Configuration:

use synaptic::cross_platform::mobile::{AndroidAdapter, MobileConfig};

let config = MobileConfig {
    enable_battery_optimization: true,
    enable_background_sync: true,
    memory_pressure_threshold: 0.7,
    cache_size_limit: 200 * 1024 * 1024, // 200MB
    enable_compression: true,
    ..Default::default()
};

let mut adapter = AndroidAdapter::new_with_config(config)?;

// Initialize JNI if available
#[cfg(feature = "mobile")]
if let Some(jvm) = get_java_vm() {
    adapter.initialize_jni(jvm)?;
}

Platform Integration:

JNI calls to Android APIs
Room database for structured storage
Android memory trim callbacks
Doze mode compatibility

Limitations:

Doze mode restrictions on background processing
Varying memory limits across devices
Android version compatibility requirements

Feature Flags

Enable specific platform features using Cargo feature flags:

[dependencies]
synaptic = { 
    version = "0.1", 
    features = [
        "wasm",           # WebAssembly support
        "mobile",         # iOS/Android support
        "compression",    # Data compression
        "encryption",     # Advanced encryption
        "analytics",      # Performance analytics
    ]
}

Usage Examples

Basic Cross-Platform Setup

use synaptic::cross_platform::{CrossPlatformAdapter, PlatformConfig};

// Auto-detect platform and create appropriate adapter
let adapter = synaptic::cross_platform::create_adapter()?;

// Configure for your use case
let config = PlatformConfig {
    max_memory_usage: 100 * 1024 * 1024, // 100MB
    enable_local_storage: true,
    enable_network_sync: true,
    storage_backends: vec![
        StorageBackend::Memory,
        StorageBackend::FileSystem,
    ],
    ..Default::default()
};

adapter.initialize(&config)?;

Platform-Specific Optimizations

use synaptic::cross_platform::Platform;

match adapter.get_platform_info().platform {
    Platform::WebAssembly => {
        // Enable web worker for heavy operations
        if let Some(wasm_adapter) = adapter.as_wasm() {
            wasm_adapter.enable_web_worker().await?;
        }
    },
    Platform::iOS => {
        // Optimize for iOS memory constraints
        if let Some(ios_adapter) = adapter.as_ios() {
            ios_adapter.optimize_for_memory_pressure()?;
        }
    },
    Platform::Android => {
        // Handle doze mode
        if let Some(android_adapter) = adapter.as_android() {
            android_adapter.configure_doze_mode_handling()?;
        }
    },
    _ => {
        // Default optimizations
    }
}

Async Operations (WASM)

// WASM supports async operations via web workers
#[cfg(feature = "wasm")]
{
    let wasm_adapter = WasmAdapter::new()?;
    
    // Store data asynchronously
    wasm_adapter.store_async("key", b"data").await?;
    
    // Retrieve data asynchronously
    let data = wasm_adapter.retrieve_async("key").await?;
    
    // Search with web worker
    let results = wasm_adapter.search_async("query", 10).await?;
}

Performance Considerations

Memory Usage

Platform	Typical Limit	Recommended Cache
WASM	50-100MB	10-20MB
iOS	100-200MB	50-100MB
Android	200-500MB	100-200MB
Desktop	1-4GB	500MB-1GB
Server	8GB+	2-4GB

Storage Performance

Backend	Read Speed	Write Speed	Durability
Memory	Very Fast	Very Fast	None
IndexedDB	Fast	Medium	High
Core Data	Fast	Fast	High
SQLite	Fast	Fast	High
File System	Medium	Medium	High

Error Handling

All cross-platform operations return Result<T, SynapticError>:

use synaptic::error::SynapticError;

match adapter.store("key", b"data") {
    Ok(()) => println!("Stored successfully"),
    Err(SynapticError::StorageError(msg)) => {
        eprintln!("Storage error: {}", msg);
    },
    Err(SynapticError::PlatformError(msg)) => {
        eprintln!("Platform-specific error: {}", msg);
    },
    Err(e) => eprintln!("Other error: {}", e),
}

Testing

Platform-specific tests are available:

# Test WASM features (requires wasm-pack)
cargo test --features wasm

# Test mobile features
cargo test --features mobile

# Test all cross-platform features
cargo test --features "wasm,mobile,compression"

Troubleshooting

Common Issues

WASM: IndexedDB not available
- Fallback to LocalStorage is automatic
- Check browser compatibility
iOS: Memory pressure warnings
- Reduce cache size limits
- Enable aggressive cleanup
Android: Background sync not working
- Check doze mode settings
- Verify background permissions
All platforms: Performance issues
- Enable compression for large data
- Tune cache sizes for your use case
- Use async operations where available

Debug Information

Enable debug logging to troubleshoot issues:

use tracing_subscriber;

tracing_subscriber::fmt::init();

// Now all cross-platform operations will log debug information

Future Roadmap

Planned Features:

WebRTC support for WASM
Enhanced iOS Core Data integration
Android Room database improvements
Cross-platform synchronization
Advanced compression algorithms

Under Consideration:

React Native support
Flutter integration
Electron compatibility
Progressive Web App optimizations
