Use ffi-rs replace ffi-napi #257

Hi, there a is a module named ffi-rs written in Rust and N-API that provides FFI (Foreign Function Interface) features for Node.js

It allows developers to call functions written in other languages such as C++, C, and Rust directly from JavaScript without writing any C++ code.

This module aims to provide similar functionality to the node-ffi module, but with a completely rewritten underlying codebase. The node-ffi module has been unmaintained for several years and is no longer usable, which is why ffi-rs was developed.

const { equal } = require('assert')
const { load, RetType, ParamsType } = require('ffi-rs')
const a = 1
const b = 100

const r = load({
  library: "./libsum.so", // path to the dynamic library file
  funcName: 'sum', // the name of the function to call
  retType: RetType.I32, // the return value type
  paramsType: [ParamsType.I32, ParamsType.I32], // the parameter types
  paramsValue: [a, b] // the actual parameter values
})

equal(r, a + b)

const c = "foo"
const d = "bar"

equal(c + d, load({
  library: dynamicLib,
  funcName: 'concatenateStrings',
  retType: RetType.String,
  paramsType: [ParamsType.String, ParamsType.String],
  paramsValue: [c, d]
}))

equal(undefined, load({
  library: dynamicLib,
  funcName: 'noRet',
  retType: RetType.Void,
  paramsType: [],
  paramsValue: []
}))
