serialization

Turning a value into text or bytes to store or send it, and back again.

Serialization converts in-memory values to a data format (JSON, TOML, bytes) and deserialization parses them back; serde separates the data types (Serialize/Deserialize) from the formats (serde_json, toml...).

Examples

With #[derive(Serialize, Deserialize)], serde_json::to_string(&r)? writes {"sensor":"porch","celsius":21.5}, and serde_json::from_str::<Reading>(&text)? reads it back.
