Cargo Features

serde_json_experimental has no features set by default.

[dependencies]
serde_json_experimental = { version = "1.0.29-rc1", features = ["preserve_order", "arbitrary_precision", "raw_value"] }

FEATURES

preserve_order = indexmap

Use a different representation for the map type of serde_json::Value.
This allows data to be read into a Value and written back to a JSON string while preserving the order of map keys in the input.

arbitrary_precision

Use an arbitrary precision number representation for serde_json::Number. This allows JSON numbers of arbitrary size/precision to be read into a Number and written back to a JSON string without loss of precision.

Affects number::TOKEN, number::NumberFromString, number::NumberDeserializer

raw_value

Provide a RawValue type that can hold unprocessed JSON during deserialization.

Affects read::Read.begin_raw_buffering, read::Read.end_raw_buffering

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
