## What it is
serde_json is the standard JSON serialization and deserialization library for Rust, built on the Serde framework. It converts between JSON text, untyped Value representations, and strongly typed Rust structs with high performance and safety.

## Use cases
- parse json in rust
- serialize rust structs to json
- deserialize json into typed structs
- validate and manipulate untyped json data
- read json from files or http endpoints
- build json api payloads in rust

## When to choose
- you need idiomatic, high-performance JSON handling in Rust
- you want compile-time derived Serialize/Deserialize for your types
- you need both typed and untyped JSON manipulation

## When to avoid
- you are not working in Rust
- you need a schema-validated binary format like protobuf instead of JSON

## Facets
- artifact type: library
- maturity: stable
- function: serialization, parser
- domain: developer-tools, web-development, apis
- platform: rust, cross-platform
- tags: json, serde, deserialization, strongly-typed, rust-library
