Type that is stored inside vector.
Public Functions
-
inline UInt256()¶
Default constructor. Initializes vector with zeros using
_mm256_setzero_si256().
-
inline UInt256(const unsigned int *pSrc)¶
Initializes vector by loading data from memory (via
_mm256_lddq_si256).- Parameters:
pSrc – Valid memory addres of minimal size of 256-bits (32 bytes).
-
inline UInt256(const unsigned int init) noexcept¶
Fills vector with passed value using
_mm256_set1_epi32().- Parameters:
init – Value to be set.
-
inline UInt256(__m256i init) noexcept¶
Just sets vector value using passed
__m256i.- Parameters:
init – Vector value to be set.
-
inline UInt256(UInt256 &init) noexcept¶
Set value using reference.
- Parameters:
init – Reference to object which value will be copied.
-
inline UInt256(const UInt256 &init) noexcept¶
Set value using const reference.
- Parameters:
init – Const reference to object which value will be copied.
-
inline UInt256(std::array<unsigned int, 8> init) noexcept¶
Sets vector values using array of unsigned integers.
When accessing vector fields using
[]order of values will be inversed.- Parameters:
init – Array of unsigned integers which values will be assigned to vector fields.
-
inline UInt256(std::array<unsigned short, 8> init) noexcept¶
Sets vector values using array of unsigned shorts. When accessing vector fields using
[]order of values will be inversed.- Parameters:
init – Array of unsigned shorts which values will be assigned to vector fields.
-
inline UInt256(std::array<unsigned char, 8> init) noexcept¶
Sets vector values using array of unsigned chars. When accessing vector fields using
[]order of values will be inversed.- Parameters:
init – Array of unsigned chars which values will be assigned to vector fields.
-
inline UInt256(std::initializer_list<unsigned int> init) noexcept¶
Sets vector values using array of unsigned integers. If list is longer than 8 other values will be ignored. If the list contains fewer than 8 elements other vector fields will be set to 0. When accessing vector fields using
[]order of values will be inversed.- Parameters:
init – Initlizer list containing unsigned integers which values will be assigned to vector fields.
-
inline __m256i get() const noexcept¶
Get underlying
__m256ivector.- Returns:
Copy of internal
__m256ivector.
-
inline void set(__m256i val) noexcept¶
Set underlying
__m256ivector value.- Parameters:
val – Vector which value will be copied.
- inline void load (const unsigned int *pSrc) N_THROW_REL
Loads data from memory into vector (memory should be of size of at least 32 bytes). Memory doesn’t need to be aligned to any specific boundary. If
sPisnullptrthis method has no effect.- Parameters:
pSrc – Pointer to memory from which to load data.
- Throws:
std::invalid_argument – If in Debug mode and
pSrcisnullptr. In Release builds this method never throws (fornullptrmethod will have no effect).
-
inline void save(std::array<unsigned int, 8> &dest) const noexcept¶
Saves data to destination in memory.
- Parameters:
dest – Reference to the list to which vector will be saved. Array doesn’t need to be aligned to any specific boundary.
- inline void save (unsigned int *pDest) const N_THROW_REL
Saves data to destination in memory. The memory doesn’t have to be aligned to any specific boundary.
See https://en.cppreference.com/w/cpp/memory/c/aligned_alloc for more details.
- Parameters:
pDest – A valid pointer to a memory of at least 32 bytes (8x
unsigned int).- Throws:
std::invalid_argument – If in Debug mode and
pDestisnullptr. In Release builds this method never throws (fornullptrmethod will have no effect).
- inline void saveAligned (unsigned int *pDest) const N_THROW_REL
Saves data to destination in memory. The memory must be aligned at 32-byte boundary.
See https://en.cppreference.com/w/cpp/memory/c/aligned_alloc for more details.
- Parameters:
pDest – A valid pointer to a memory of at least 32 bytes (8x
unsigned int).- Throws:
std::invalid_argument – If in Debug mode and
pDestisnullptr. In Release builds this method never throws (fornullptrmethod will have no effect).
-
inline bool operator==(const int b) const¶
-
inline bool operator!=(const int b) const¶
-
inline unsigned int operator[](const unsigned int index) const¶
-
inline std::string str() const noexcept¶
Return string representation of vector.
- Returns:
String representation of vector.
Public Static Attributes
-
static int size = 8¶
Number of individual values stored by object. This value can be used to iterate over elements.
