Create machine-readable JSON diffs
```rust let a = serde_json::json!({ "list": [1, 2, 3], "object": {"a": "b"} });
let b = serde_json::json!({ "list": [1, 2, 3], "object": {"a": "b"} });
assert!(serdejsondiff::values(a, b).is_none()); ```
serde_json_diff::objects and serde_json_diff::arrays are also exposed
specifically for comparing serde_json::Map<String, serde_json::Value>
and Vec<serde_json::Value>s respectively.
sh
serde_json_diff my_json_file.json my_other_json_file.json
Tip: Since the command name serde_json_diff is a bit long, I personally have it aliased in my shell config:
sh
alias jdiff="serde_json_diff"
Comparing this file:
json
{
"A": "a",
"B": "a",
"D": 1,
"E": 1,
"F": [],
"G": ["a", "a"]
}
To this file:
json
{
"A": "a",
"C": "b",
"D": 2,
"E": "1",
"F": [true],
"G": ["a", "ab"]
}
Results in this diff (serialised as JSON):
json
{
"B": {
"entry_difference": "extra"
},
"D": {
"entry_difference": "value",
"value_diff": {
"difference_of": "scalar",
"source": 1,
"target": 2
}
},
"E": {
"entry_difference": "value",
"value_diff": {
"difference_of": "type",
"source_type": "number",
"target_type": "string",
"target_value": "1"
}
},
"F": {
"entry_difference": "value",
"value_diff": {
"difference_of": "array",
"array_difference": "longer",
"different_pairs": null,
"missing_elements": 1
}
},
"G": {
"entry_difference": "value",
"value_diff": {
"difference_of": "array",
"array_difference": "pairs_only",
"different_pairs": {
"1": {
"difference_of": "scalar",
