serde_json_merge

Merge, index, iterate, and sort a serde_json::Value (recursively).

This library supports in-place merging and sorting using DFS and BFS traversal unline most implementations out there that use recursion and can stack overflow.

[dependencies]
serde_json_merge = "0"

Usage

For usage examples, check the examples and documentation.

Acknowledgements

After i wrote this crate for another project and decided to publish it, I found json_value_merge.

Looking through it, I added merge_index inspired by their merge_in API.

TODO

• write benchmarks

• add globbing iter

• add iters for keys and values

• implement sorting values with indices

• implement bfs

• add rayon support using par-dfs

• write documentation

• add examples in the documentation

DONE:

• inline everything
• do we really need the any type? so useless right now :(
  • maybe use them for the very precise type?
• add custom comparator for merging
• split the sorting into extra module
• implement unstable sorting
• add feature gates for sort and merge
• add few more tests for kind and so on
• partial eq can be written top level
• add limit to dfs
• do not expose wrapper for Value but use extension
• add depth parameter to recursive merge
