# Sonic-rs RoadMap
This document shows key roadmap of `sonic-rs` development. It may help users know more about the future features. But the actual work is driven by real-world needs, we may adjust our goals sometimes.
## stability
1. support utf-8 validate (Done with `utf8` feature)
2. add more fuzzing tests
3. make unittest coverage to 90%
## Portability
0. make sonic-rs support stable Rust (The most important now)
1. optimize the performance in aarch64
2. runtime CPU detection
3. support fallback in unsupported arch
## Features
1. support more JSON RFC:
- [`JSON Path`](https://datatracker.ietf.org/wg/jsonpath/about/).
- [`JSON Merge Patch`](https://www.rfc-editor.org/rfc/rfc7396).
2. support the `Deserializer` trait for document (document can be deserialized into a Rust type).
## Performance
1. support zero-copy for FastStr
2. maybe reimplement the `Deserialize` or `Serialize` trait ?.
