serde_json is a Rust library that provides JSON serialization and deserialization through Serde.
serde_json connects an Actix Web application to a REST service by interpreting the service’s JSON response as strongly typed Rust data. section 7.7
A typical integration proceeds as follows:
Fetch the response body through Actix Web’s HTTP client, convert the bytes, and deserialize the tutor list into Vec<Tutor>. section 7.7
Tutor list integration
A handler requests http://localhost:3000/tutors/, deserializes the returned tutors, and passes them to a Tera template. The template displays each tutor’s tutor_name field.
How Rust Servers, Services, and Apps covers it
How deep it goes
Demonstrates dependency setup, matching structs, response-body handling, and deserialization, without exploring parser internals.
Examples
Uses a Tutor struct, a /tutors/ endpoint, a Vec<Tutor> result, and a template displaying tutor_name.
What it assumes
Assumes Rust web-server, HTTP request, REST API, and Rust struct familiarity while demonstrating JSON mapping in context.
What you can do after
Apply it via serde_json to deserialize an HTTP JSON payload into strongly typed Rust structures.
How it connects
Ties JSON deserialization to Serde, Rust structs, Actix Web, HTTP clients, REST APIs, and Tera templates.
JSONuses · JSON is a standardized, language-independent text format for representing structured data using objects, arrays, strings, numbers, Boolean values, and null.
serdeuses · Serde is a Rust framework for serializing and deserializing data structures across external data formats.
deserializationuses · Deserialization is the process of reconstructing structured data or in-memory values from a serialized representation.
