T – Datatype to allocate

Public Types

using value_type = T

Public Functions

inline explicit constexpr AlignedAllocator(uint32_t alignment)

Constructor of AlignedAllocator class.

Parameters

alignment – Memory alignment we want.

inline uint32_t alignment() const

Get alignment of the allocator.

template<typename U>
inline explicit constexpr AlignedAllocator([[maybe_unused]] const AlignedAllocator<U> &rhs) noexcept

inline T *allocate(std::size_t size) const

Allocate memory with for the given number of datatype T.

Parameters

size – The number of T objects for the allocation

Returns
