Function serialize_argument 

pub fn serialize_argument<T: Serialize>(arg: &T) -> Value

Serializes an argument for Playwright’s evaluateExpression method.

This is the main entry point for serializing arguments. It wraps the serialized value with the required “value” and “handles” fields.

Arguments

• arg - A value that implements serde::Serialize or a serde_json::Value

Returns

A JSON object with “value” and “handles” fields in Playwright’s format:

{
  "value": { /* serialized value */ },
  "handles": []
}

Examples

use playwright_rs::protocol::serialize_argument;
use serde_json::json;

// String argument
let arg = serialize_argument(&json!("hello"));
// Returns: {"value": {"s": "hello"}, "handles": []}

// Number argument
let arg = serialize_argument(&json!(42));
// Returns: {"value": {"n": 42}, "handles": []}

// Object argument
let arg = serialize_argument(&json!({"name": "test"}));
// Returns: {"value": {"o": [{"k": "name", "v": {"s": "test"}}], "id": 0}, "handles": []}
