use libmagic_rs::output::json::format_value_as_hex;
use libmagic_rs::parser::ast::Value;

let bytes_value = Value::Bytes(vec![0x7f, 0x45, 0x4c, 0x46]);
assert_eq!(format_value_as_hex(&bytes_value), "7f454c46");

let string_value = Value::String("PNG".to_string());
assert_eq!(format_value_as_hex(&string_value), "504e47");
