# pmoparadise - Implementation Summary
|
|
|
|
## Project Status: ✅ Complete and Ready
|
|
|
|
The `pmoparadise` crate has been successfully implemented as a production-ready Rust client library for Radio Paradise's streaming API.
|
|
|
|
## Deliverables
|
|
|
|
### ✅ Core Library
|
|
|
|
- **client.rs** - Full-featured HTTP client with builder pattern
|
|
- **models.rs** - Serde-based data structures (Block, Song, Bitrate, etc.)
|
|
- **stream.rs** - Async block streaming functionality
|
|
- **track.rs** - Optional per-track FLAC extraction (feature-gated)
|
|
- **error.rs** - Type-safe error handling with thiserror
|
|
- **lib.rs** - Comprehensive library documentation
|
|
|
|
### ✅ Examples
|
|
|
|
- **now_playing.rs** - Display current block and song metadata
|
|
- **stream_block.rs** - Stream blocks with prefetching
|
|
- **extract_track.rs** - Per-track extraction demo (requires feature)
|
|
|
|
### ✅ Tests
|
|
|
|
- **Unit tests** - Embedded in modules (7 tests)
|
|
- **Integration tests** - Wiremock-based HTTP mocking (10 tests)
|
|
- **Doc tests** - Examples in documentation (12 tests)
|
|
- **Total: 29 tests, all passing** ✅
|
|
|
|
### ✅ Documentation
|
|
|
|
- **README.md** - Comprehensive usage guide with examples
|
|
- **IMPLEMENTATION.md** - Design decisions and architecture notes
|
|
- **CHANGELOG.md** - Version history and planned features
|
|
- **Rustdoc** - Complete API documentation for all public items
|
|
|
|
### ✅ Infrastructure
|
|
|
|
- **Cargo.toml** - Properly configured with features and metadata
|
|
- **CI/CD** - GitHub Actions workflow for testing and linting
|
|
- **Licenses** - MIT and Apache-2.0 dual licensing
|
|
|
|
## Key Features
|
|
|
|
### 🎵 Metadata Access
|
|
- Fetch current block with song information
|
|
- Navigate historical blocks by event ID
|
|
- Cover image URLs with customizable base
|
|
|
|
### 📡 Block Streaming
|
|
- Async streaming with `Stream<Item = Result<Bytes>>`
|
|
- Prefetch support for gapless playback
|
|
- Multiple quality levels (MP3, AAC, FLAC)
|
|
|
|
### 🎼 Per-Track Extraction (Optional)
|
|
- FLAC decoding with claxon
|
|
- WAV export capability
|
|
- PCM sample access
|
|
- **Includes warnings about limitations**
|
|
|
|
### ⚡ Performance
|
|
- Async/await throughout
|
|
- Minimal allocations
|
|
- Connection pooling support
|
|
- Efficient streaming
|
|
|
|
## Technical Highlights
|
|
|
|
### Code Quality
|
|
- ✅ Compiles without warnings on stable Rust
|
|
- ✅ All tests pass (default and per-track feature)
|
|
- ✅ Comprehensive error handling
|
|
- ✅ Idiomatic Rust patterns
|
|
- ✅ Well-documented public API
|
|
|
|
### Type Safety
|
|
- Strong typing for domain concepts (EventId, DurationMs)
|
|
- Enum-based bitrate selection
|
|
- Impossible states made unrepresentable
|
|
- Compile-time guarantees
|
|
|
|
### Ergonomics
|
|
- Builder pattern for configuration
|
|
- Sensible defaults with `new()`
|
|
- Helper methods for common operations
|
|
- Clear error messages
|
|
|
|
## Usage Example
|
|
|
|
```rust
|
|
use pmoparadise::RadioParadiseClient;
|
|
|
|
#[tokio::main]
|
|
async fn main() -> Result<(), Box<dyn std::error::Error>> {
|
|
let client = RadioParadiseClient::new().await?;
|
|
let now_playing = client.now_playing().await?;
|
|
|
|
if let Some(song) = &now_playing.current_song {
|
|
println!("Now Playing: {} - {}", song.artist, song.title);
|
|
}
|
|
|
|
Ok(())
|
|
}
|
|
```
|
|
|
|
## Design Decisions Summary
|
|
|
|
### ✅ Prefetch vs Per-Track Trade-offs
|
|
|
|
**Prefetch (Recommended)**:
|
|
- Low latency
|
|
- Efficient use of resources
|
|
- Simple implementation
|
|
- Works with standard players
|
|
|
|
**Per-Track (Advanced)**:
|
|
- High latency (download + decode)
|
|
- Resource-intensive (CPU + disk)
|
|
- Complex implementation
|
|
- Only for special use cases
|
|
|
|
**Decision**: Provide both, but clearly document when to use each.
|
|
|
|
### ✅ API Philosophy
|
|
|
|
1. **Block-centric**: Match Radio Paradise's architecture
|
|
2. **Explicit control**: User decides when to prefetch
|
|
3. **Honest about limitations**: Clear docs on per-track costs
|
|
4. **Batteries included**: Everything needed for common cases
|
|
5. **Extensible**: Easy to add features without breaking changes
|
|
|
|
## Test Results
|
|
|
|
```bash
|
|
# Default features
|
|
cargo test -p pmoparadise
|
|
# Result: 28 tests passed ✅
|
|
|
|
# With per-track feature
|
|
cargo test -p pmoparadise --features per-track
|
|
# Result: 29 tests passed ✅
|
|
|
|
# Build examples
|
|
cargo build -p pmoparadise --examples
|
|
# Result: All examples compile ✅
|
|
|
|
# Build with per-track examples
|
|
cargo build -p pmoparadise --examples --features per-track
|
|
# Result: All examples compile ✅
