base_n::basic_codec::max_decoded_size

static constexpr mgs::ssize_t max_decoded_size(mgs::ssize_t encoded_size);

Computes the maximum decoded size corresponding to encoded_size.

---

Parameters

• encoded_size - Encoded size, must be > 0.

Return value

The maximum decoded size, or -1 if encoded_size does not represent a valid encoded size.

Example

#include <mgs/base64.hpp>

using namespace mgs;

static_assert(base64::max_decoded_size(4) == 3, "");
static_assert(base64::max_decoded_size(3) == -1, "");
