rsjson is a Rust library designed to be called from OpenResty Lua for JSON encoding and decoding. It provides a high-performance, safe, and easy-to-use solution for working with JSON data in Lua.

• High Performance: Written in Rust, rsjson is designed for speed.
• Safety: Leverages Rust's strong type system and error handling.
• Ease of Use: Simple API with only two methods, encode and decode.

1. Clone the repository and navigate to its directory.
2. Run cargo build --release.
3. The dynamic library (librsjson.so on Linux, librsjson.dylib on macOS) will be in the target/release directory.

Copy the rsjson.lua file to your OpenResty Lua project.

Here's a simple example demonstrating how to use rsjson:

local json = require('rsjson')

local json_string = '{"user": "demo", "debug": true, "unique_id": 123456, "meta": {"items": ["1","2","3"]}}'

-- Decode JSON string to Lua table
local doc = json.decode(json_string)
print(doc)

-- Encode Lua table to JSON string
print(json.encode(doc))

json.decode(json_string: string) -> table Decodes a JSON-formatted string and returns a Lua table.

json.encode(lua_table: table) -> string Encodes a Lua table into a JSON-formatted string.
