Crate jadipa 

Jadipa (JSON DiffPatch)

This crate provides tooling for JSON pointers, patches, and other utils. It is built around serde_json::Value and exposes small modules for standards-based JSON document addressing and mutation.

The [pointer] module is always available and implements JSON Pointer support as defined by RFC 6901. Use pointer::Pointer to represent paths into a JSON document and to resolve immutable or mutable values from a serde_json::Value.

With the patch feature enabled, the patch module provides JSON Patch support as defined by RFC 6902. patch::Patch parses ordered patch documents and applies their operations sequentially to JSON values.

Example

use jadipa::patch::Patch;
use serde_json::json;

let target = json!({ "name": "old" });
let patch = Patch::new(r#"[{"op":"replace","path":"/name","value":"new"}]"#)?;
let patched = patch.apply(&target)?;

assert_eq!(patched, json!({ "name": "new" }));
assert_eq!(target, json!({ "name": "old" }));

• patch (enabled by default) — Enables JSON Patch (RFC 6902)
• diff (enabled by default) — Feature that allows comparing two JSON objects and create a diff in the form of a JSON Patch.
• merge_patch — Enables JSON Merge Patch (RFC 7396)
