### Synopsis

    void
    reset(
        value const* p) noexcept; (1)

    void
    reset(
        array const* p) noexcept; (2)

    void
    reset(
        object const* p) noexcept; (3)

    void
    reset(
        string const* p) noexcept; (4)

    template<
        class T>
    void
    reset(
        T const* p) noexcept; (5)

    void
    reset(
        string_view sv) noexcept; (6)

    void
    reset(
        std::nullptr_t np) noexcept; (7)

### Description

This function prepares the serializer to emit a new serialized JSON representing its argument: `*p` (1)–(5), `sv` (6), or `np` (7). Ownership is not transferred. The caller is responsible for ensuring that the lifetime of the object pointed to by the argument extends until it is no longer needed.

Any memory internally allocated for previous uses of this `serializer` object is preserved and re-used for the new output.

Overload (5) uses direct serialization.

### Parameters

Name | Description
--- | ---
`p` | A pointer to the element to serialize.
`sv` | The characters representing a string.
`np` | Represents a null value.
