JSONFilter
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. For a full syntax guide, see the Filter Documentation
Usage
To use jsonfilter
, add it to your Cargo.toml
and add the following to your Rust code:
use jsonfilter::{order, matches};
Comparing JSON Values
You can compare two JSON values using the order
function:
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:
use serde_json::json;
use jsonfilter::matches;
let filter = json!({"name": "John", "age": 30});
let obj = json!({"name": "John", "age": 30, "city": "New York"});
assert!(matches(&filter, &obj));
