Attribute Macro request_body_json 

#[request_body_json]

This attribute macro extracts and deserializes the request body content as JSON into a variable with the specified type. The body content is parsed as JSON using serde.

Usage

use hyperlane::*;
use hyperlane_macros::*;
use serde::Deserialize;

#[derive(Deserialize, Clone)]
struct UserData {
    name: String,
    age: u32,
}

#[request_body_json(user_data: UserData)]
async fn handle_user(ctx: Context) {
    if let Ok(data) = user_data {
        // Use the parsed user data
    }
}

The macro accepts a variable name and type in the format variable_name: Type. The variable will be available in the function scope as a Result<Type, JsonError>.
