Typedef Documentation

◆ MemoryStreamElement

template<MemoryStreamStorageElement StorageElement>

using xentara::utils::io::MemoryStreamElement = typedef typename detail::DeducedMemoryStreamElement<StorageElement>::Type

A suitable element type for MemoryInputStream and MemoryOutputStream for a storage element type.

This type alias deduces the best memory stream element type for memory containing a certain type of data. The types chosen are as follows:

character types (char, wchar_t, char8_t, char16_t, char32_t) are used directly
non-character 8-bit types are mapped to std::byte
16-bit types are mapped to char16_t
32-bit types are mapped to char32_t
