eve::aligned_allocator< T, Lanes > Struct Template Reference

Standard-compliant allocator handling the allocation and deallocation of segment of aligned memory. More...

#include <eve/memory/aligned_allocator.hpp>

Detailed Description

template<typename T, typename Lanes = expected_cardinal_t<T>>
struct eve::aligned_allocator< T, Lanes >

Required header: #include <eve/memory/aligned_allocator.hpp>

By default, allocation will be aligned on current architecture's SIMD compatible alignment but can be specified otherwise.

aligned_allocator is designed ot be used through std::allocator_traits, so it provides the minimal amount of members and members types.

Template Parameters

T	Type to allocate
Lanes	Alignment constraint to uphold. Default value is computed to be compatible with current SIMD ABI requirements.

Classes
struct	rebind
	Convert an aligned_allocator type to another. More...

Public Types
using	value_type = T
	type to allocate, i.e T

Public Member Functions
	aligned_allocator () noexcept
	Default constructor.
template<typename U >
	aligned_allocator (aligned_allocator< U, Lanes > const &) noexcept
	Copy constructor.
value_type *	allocate (std::size_t n)
	Allocates aligned, uninitialized storage for n elements of type T.
void	deallocate (value_type *p, std::size_t) noexcept
	Deallocates aligned storage.

Static Public Member Functions
static constexpr auto	alignment () noexcept
	Return the value of the alignment constraint.
