Detailed Description

template<plain_scalar_value T>
struct eve::logical< T >

Wrapper for SIMD compatible logical types.

Required header: #include <eve/logical.hpp>

eve::logical is an architecture-agnostic representation of a boolean mask and provides standardized API to access informations, compute values and manipulate such mask. Contrary to bool, an instance of logical has the same sizeof as T, allowing seamless interaction with an instance eve::logical<eve::wide< T >>.

Template Parameters

T	Type of value to store a mask from

Public Types
using	value_type = T
	The type associated to the boolean mask.
using	mask_type = T
	The type representing the numerical value of mask.
using	bits_type = as_integer_t< T, unsigned >
	The type representing the bitwise representation of the mask.

Public Member Functions
