Module rewrite 

Streaming JSON rewriting.

This module supports streaming replacement and removal for scalar values and whole object/array subtrees. A replaced or removed container is suppressed as the tokenizer streams through it, so non-capturing rewrites do not need to buffer the subtree.

Example

use rama_json::{
    path::JsonPath,
    rewrite::{JsonHandlers, raw_json, rewrite_bytes},
};

let input = br#"{"id":1,"prompt":{"text":"secret"},"extensions":[{"id":1},{"id":2}]}"#;
let output = rewrite_bytes(
    input,
    JsonHandlers::new()
        .on(JsonPath::builder().member("prompt").build(), |value| {
            value.remove();
            Ok(())
        })
        .on(
            JsonPath::builder().member("extensions").index(0).build(),
            |value| value.replace(raw_json(br#"{"id":9}"#)),
        ),
)?;

assert_eq!(output, br#"{"id":1,"extensions":[{"id":9},{"id":2}]}"#);
