+/**
+ * @class guard
+ * @brief A copyable and comparable wrapper for std::atomic
+ * @tparam T The underlying value type
+ *
+ * The guard<T> class provides a wrapper around std::atomic<T> that adds copyability
+ * and comparability while maintaining thread-safety for individual operations.
+ * This allows for more intuitive usage patterns where atomic values need to be
+ * treated occasionally as regular values.
+ *
+ * Unlike std::atomic, guard<T> can be:
+ * - Copied (using atomic load operations)
+ * - Compared (between atoms and with raw values)
+ * - Used with familiar operator syntax
+ *
+ * @note While individual operations remain atomic, operations like comparison
+ * are not atomic as a whole, as they involve multiple loads. This wrapper is
+ * appropriate when you need the performance of atomics but occasionally need
+ * value semantics.
+ *
+ * Typical use cases:
+ * - Configuration values that are rarely updated but frequently read
+ * - Statistics and counters that need occasional comparison
+ * - Scenarios where atomic operations are needed but with more familiar syntax
+ *
+ * Example usage:
+ * @code
+ * guard<int> counter(0);
+ *
+ * // Thread-safe operations
+ * counter++;
+ * counter += 5;
+ *
+ * // Copyable
+ * guard<int> copy = counter;
+ *
+ * // Comparable
+ * if (counter > 10) { ... }
+ * if (counter == copy) { ... }
+ * @endcode

+// - We don't allow decimals in integer parsing
+// - We don't allow negative exponents
+// Thse cases can produce fractions which slow performance and add confusion
+// as to how the integer ought to be parsed (truncation, rounding, etc.)
+// This integer parsing is designed to be straightfoward and fast
+// Values like 1e6 are allowed because it enables less typing from the user
+// and has a clear integer value
+
+// Valid JSON integer examples
+// 1234
+// 1234e1
+// 1e9
+
+// Invalid for this atoi algorithm
+// 1.234
+// 1234e-1
+// 0.0
+
+// The standard JSON specification for numbers and the associated rules apply
+
+// *** We ensure that a decimal value being parsed will result in an error
+// 1.2 should not produce 1, but rather an error, even when a single field is parsed
+// This ensures that we get proper errors when parsing and don't get confusing errors
+// It isn't technically required, because end validation would handle it, but it produces
+// much clearer errors, especially when we don't perform trailing validation.

+ * floating-point value is the closest floating-point values (using either float

+ *
+ * Given a successful parse, the pointer (`ptr`) in the returned value is set to

+ * parsed value. In case of error, the returned `ec` contains a representative
+ * error, otherwise the default (`std::errc()`) value is stored.
+ *
+ * The implementation does not throw and does not allocate memory (e.g., with
+ * `new` or `malloc`).
+ *
+ * Like the C++17 standard, the `fast_float::from_chars` functions take an
+ * optional last argument of the type `fast_float::chars_format`. It is a bitset
+ * value: we check whether `fmt & fast_float::chars_format::fixed` and `fmt &
+ * fast_float::chars_format::scientific` are set to determine whether we allow
