Function parse_filter 

pub fn parse_filter(json_str: &str) -> Result<FilterExpr, ParseError>

Parse a Mongo-style filter from a JSON string.

This is a convenience function that calls FilterExpr::parse.

Example

use mik_sql::prelude::*;

// Simple filter
let filter = parse_filter(r#"{"active": true}"#).unwrap();

// Complex filter with operators
let filter = parse_filter(r#"{
    "status": {"$in": ["active", "pending"]},
    "age": {"$gte": 18}
}"#).unwrap();

// Logical operators
let filter = parse_filter(r#"{
    "$or": [
        {"role": "admin"},
        {"role": "moderator"}
    ]
}"#).unwrap();

Errors

Returns ParseError if the JSON is invalid.
