jsone

Zero-loss JSON serialization for Rust values that JavaScript or JSON cannot normally encode/decode without losing precision.

jsone provides serde helpers for values that need a JSON representation which can be decoded safely on the JavaScript side. The crate exposes a single wrapper type, Jsone<T>, which wraps a field or value and handles lossless Rust-side serialization and deserialization.

Pair this crate with the frontend encoder or decoder so JavaScript can turn the encoded JSON representation back into regular JavaScript values.

This crate was developed around research I did while funded from Flight Science for work on Specta v2!
