JSON Operators

A collection of tools to help operate on serde_json::Values.

partial_cmp

JOPS provides a function for comparing two serde_json::Value.

Examples

The partial_cmp function.

```rust use std::cmp::Ordering; use serde_json::Value;

let a = Value::Null; let b = Value::Null; let res : Ordering = jops::partial_cmp(&a, &b); ```

JsonValue wrapper provides partial_cmp.

```rust use jops; use serde_json::Value;

let a = jops::JsonValue(&Value::Null); let b = jops::JsonValue(&Value::Null); let res = a > b; ```

JsonPath

An SQLite JSON Path implementation. Access Values inside an Object or Array.

Operators

• $ represents the root Value
• .<name> points to a sub value with key name inside an Object
• <name>[<index>] points to a value inside an Array name at index (zero indexed).
• <name>[#-<offset>] points to a value inside an Array name at length of array minus offset.
• <index> points to a value inside a root Array at index (zero indexed).

Examples

rust let value = serde_json::json!({ "a": "example", "b": [0,1,2] }); value.path("$"); // Returns a reference to value value.path("$.a"); // Returns a reference to the String value "example" value.path("$.b[1]"); // Returns a reference to the Number value 1 inside the array b value.path("$.b[#-1]"); // Returns a reference to the Number value 1 inside the array b let value = serde_json::json!([0,2]); value.path("1"); // Returns a reference to the Number value 2 inside the array
