Docs say that deserialization without alloc is supported

[leighmcculloch]

The docs appear to say: https://github.com/CosmWasm/serde-json-wasm/blob/2ab22a6f3a741b4db507c464185d86beefc5bab6/src/lib.rs#L11 https://github.com/CosmWasm/serde-json-wasm/blob/2ab22a6f3a741b4db507c464185d86beefc5bab6/src/lib.rs#L15-L18

However, looking at the API, DeserializedOwned is required: https://github.com/CosmWasm/serde-json-wasm/blob/2ab22a6f3a741b4db507c464185d86beefc5bab6/src/de/mod.rs#L654-L656

What's the right way to use the lib to do deserialisation with &str fields being a zero copy?

Thanks!

The docs are outdated, thank you for pointing this out. They are from the original serde-json-core.

For JSON neither serialization nor deseralization can be done zero-copy without heavily restricting the supported contents because of escaping. E.g.

• Serialize string \ (1 byte) gives you "\\" (2 bytes)
• Deserialize JSON string "23\u00B0C" (9 bytes) returns 23°C (4 bytes)
