| description.long | A Python library that identifies character encoding in byte sequences and converts content to Unicode. It determines the most readable interpretation of text regardless of its original encoding, and includes language detection and binary file recognition capabilities. | Serde enables Rust developers to serialize and deserialize data structures to various formats through compile-time trait implementations, eliminating runtime reflection overhead and achieving performance comparable to hand-written serializers. |
