描述
Hello,
I am trying to compare an array of objects to check for a specific set of objects to be present in any of them, but not across all of them, specifically lets take this rule:
```
const arrayRule = {
conditions: {
any: [
{
all: [
{
fact: 'data',
path: '$.[*].equalityTest',
operator: 'equal',
value: 50,
},
{
fact: 'data',
path: '$.[*].anotherTest',
operator: 'equal',
value: 50,
},
],
},
],
},
event: {
type: 'arrayRule',
},
};
```
This is the first iteration of the rule I came up with, it is incorrect, but I wanted to give an idea of what I am aiming for.
Specifically here, we have a rule where I want `equalityTest` to equal `50` and `anotherTest` to also equal `50`. But I want them to equal those values in the same object, such that:
*THIS SHOULD RETURN FALSE*
```
const facts = {
data: [
{
anotherIntegerFact: 1,
equalityTest: 50,
},
{
anotherIntegerFact: 50,
equalityTest: 40,
},
],
};
```
*THIS SHOULD RETURN TRUE*
```
const facts = {
data: [
{
anotherIntegerFact: 50,
equalityTest: 50,
},
{
anotherIntegerFact: 40,
equalityTest: 40,
},
],
};
```
Would love any suggestions or ideas on a way to tackle this. One thought was I could write my own `operator` and add it to the registry of operators on our end, but before I did so, I wanted to validate that is needed.
Thanks

调研方向
未指定文件或测试入口点。首先检查与数组路径求值相关的规则条件和运算符注册表;使用提供的两个 facts 示例,将完成定义为同一对象匹配:第一个返回 false,第二个返回 true。
