`jsonfilter` is a Rust crate designed to facilitate filtering and comparing JSON values based on specified criteria. It provides functions for comparing JSON values, applying filters to JSON objects, and determining if a filter matches a given JSON object. Think of MongoDBs `find()` function but as a filter function.
## Usage
To use `jsonfilter`, add it to your `Cargo.toml` and add the following to your Rust code:
```rust
use jsonfilter::{order, matches};
```
### Comparing JSON Values
You can compare two JSON values using the `order` function:
```rust
use serde_json::json;
use std::cmp::Ordering;
use jsonfilter::order;
let a = json!(10);
let b = json!(5);
assert_eq!(order(&a, &b), Ordering::Greater);
```
### Matching Filters
To check if a JSON object matches a filter, use the `matches` function:
```rust
use serde_json::json;
use jsonfilter::matches;
let filter = json!({"name": "John", "age": 30});
let obj = json!({"name": "John", "age": 30, "city": "New York"});
