Vector

Portable 16-byte SIMD vector (v128). T must be byte, int, long, float, or double.

public struct Vector<T: unmanaged>

lane_count

Number of elements held by this vector type.

public static extern fun lane_count(): int

constructor

Splats value into every lane.

public constructor(value: T)

load

Loads Vector<T>.count consecutive elements from src starting at offset.

public static fun load(borrow src: T[], offset: int): Vector<T>

store

Writes this vector's lanes into dest starting at offset.

public fun store(borrow dest: T[], offset: int): void

lane

Returns lane i (0 .. count).

public fun lane(i: int): T

with_lane

Returns a copy with lane i replaced by value.

public fun with_lane(i: int, value: T): Vector<T>

min

Lane-wise minimum of a and b.

public static fun min(a: Vector<T>, b: Vector<T>): Vector<T>

max

Lane-wise maximum of a and b.

public static fun max(a: Vector<T>, b: Vector<T>): Vector<T>

sum

Horizontal sum of every lane.

public fun sum(): T
