int64x2
struct int64x2Available without an import.
A 128-bit SIMD value containing 2 int64 lanes. Arithmetic operates lane-wise, with integer overflow wrapping within each lane. Lane and WithLane require constant indices; bracket indexing supports checked runtime indices. Comparisons return all-one/all-zero integer masks. Bit reinterpretation involving floating-point lanes canonicalizes NaNs.
Members
Splatmethod
public static fn Splat(int64 value) : int64x2Copies one scalar value into every lane.
Zeromethod
public static fn Zero() : int64x2Returns a vector whose lanes are all zero.
constructorconstructor
public constructor (int64 l0, int64 l1)Creates a vector from scalar lanes in ascending index order.
Lanemethod
public fn Lane(int32 index) : int64Reads a compile-time constant lane index in [0, 2). Invalid or nonconstant indices are rejected; use bracket indexing for runtime indices.
ReduceSummethod
public fn ReduceSum() : int64Sums every lane into the scalar result. Arithmetic wraps at the scalar result width; narrow lanes are widened before addition.
Absmethod
public fn Abs() : int64x2Returns each lane's magnitude. A minimum signed lane remains the negative minimum because its positive magnitude does not fit.
Eqmethod
public fn Eq(int64x2 other) : int64x2Compares corresponding lanes for equal, returning all-one bits for true and all-zero bits for false. Ordered comparisons use the lane type's signedness.
Nemethod
public fn Ne(int64x2 other) : int64x2Compares corresponding lanes for unequal, returning all-one bits for true and all-zero bits for false. Ordered comparisons use the lane type's signedness.
Ltmethod
public fn Lt(int64x2 other) : int64x2Compares corresponding lanes for less, returning all-one bits for true and all-zero bits for false. Ordered comparisons use the lane type's signedness.
Lemethod
public fn Le(int64x2 other) : int64x2Compares corresponding lanes for less or equal, returning all-one bits for true and all-zero bits for false. Ordered comparisons use the lane type's signedness.
Gtmethod
public fn Gt(int64x2 other) : int64x2Compares corresponding lanes for greater, returning all-one bits for true and all-zero bits for false. Ordered comparisons use the lane type's signedness.
Gemethod
public fn Ge(int64x2 other) : int64x2Compares corresponding lanes for greater or equal, returning all-one bits for true and all-zero bits for false. Ordered comparisons use the lane type's signedness.
AnyTruemethod
public fn AnyTrue() : boolTests whether any lane has a nonzero bit pattern.
AllTruemethod
public fn AllTrue() : boolTests whether every lane has a nonzero bit pattern.
Bitmaskmethod
public fn Bitmask() : int32Packs each lane's most significant bit into the corresponding bit of an integer; lane zero becomes bit zero.
WithLanemethod
public fn WithLane(int32 index, int64 value) : int64x2Returns a copy with one lane replaced. The index must be a compile-time constant in [0, 2); use bracket assignment for runtime indices.
Shufflemethod
public fn Shuffle(int32 l0, int32 l1) : int64x2Returns lanes selected in argument order. Every index must be a compile-time constant in [0, 2); repeats are allowed.
Selectmethod
public fn Select(int64x2 a, int64x2 b) : int64x2Selects bits from a where this mask has one bits and from b where it has zero bits. Comparison masks select entire lanes; arbitrary masks can mix bits within a lane.
Blendmethod
public fn Blend(float64x2 a, float64x2 b) : float64x2Selects floating-point bits from a where this integer mask has one bits and from b where it has zero bits. Comparison masks select entire lanes.
AsInt8x16method
public fn AsInt8x16() : int8x16Reinterprets this 128-bit value with the destination lane shape rather than converting numerically. Floating-point NaN lanes are canonicalized on either side of the reinterpretation; NaN payload bits are not preserved.

public fn AsUint8x16() : uint8x16Reinterprets this 128-bit value with the destination lane shape rather than converting numerically. Floating-point NaN lanes are canonicalized on either side of the reinterpretation; NaN payload bits are not preserved.
AsInt16x8method
public fn AsInt16x8() : int16x8Reinterprets this 128-bit value with the destination lane shape rather than converting numerically. Floating-point NaN lanes are canonicalized on either side of the reinterpretation; NaN payload bits are not preserved.
AsUint16x8method

AsFloat32x4method

Loadmethod
public static fn Load(Span<uint8> data, int32 byteOffset) : int64x2Reads 16 bytes starting at byteOffset as this lane type. The complete range must fit the span or the operation panics. No alignment requirement is imposed.

LoadElemsmethod
public static fn LoadElems(Span<int64> data, int32 elemIndex) : int64x2Reads 2 consecutive elements starting at elemIndex. The whole element range must fit or the operation panics; indices count elements, not bytes.
