json-pointer

A crate for parsing and using JSON pointers, as specified in RFC 6901.

Creating a JSON Pointer

JSON pointers can be created with a literal [&str], or parsed from a String.

```rust let from_strs = JsonPointer::new([ "foo" "bar", ]); let parsed = "/foo/bar".parse::>().unwrap();

asserteq!(fromstrs.unwrap(), parsed.unwrap()); ```

Using a JSON Pointer

The JsonPointer type provides .get() and .get_mut(), to get references and mutable references to the appropriate value, respectively.

```rust // where ptr is either of the JsonPointers from above.

let document = json!({ "foo": { "bar": 0, "baz": 1, }, "quux": "xyzzy" });

let indexed = ptr.get(&document).unwrap();

assert_eq!(indexed, &json!(0)); ```
