Method GetResidueMaskBits

Namespace: Zyl.VectorTraits.Impl

Assembly: VectorTraits.dll

GetResidueMaskBits<T>(int)

Get residue bits mask by index (根据索引获取剩余的位集掩码). The index value ranges from 0 to sizeof(T)*8-1 (索引值的范围是 0 ~ sizeof(T)*8-1). The equivalent of Vector128s<T>.GetResidueMaskBits(sizeof(T)*8 - index).

[Obsolete("It is only suitable for unit testing because it contains branching statements and has poor performance. In general, it is recommended to use the non-generic version of the methods (因它含有分支语句, 性能较差, 仅适用于单元测试. 一般情况下, 建议使用非泛型版方法).")]
public static Vector128<T> GetResidueMaskBits<T>(int index) where T : struct

Parameters

index int: The index (索引). The value ranges from 0 to sizeof(T)*8-1 (值的范围是 0 ~ sizeof(T)*8-1). 为了性能, 本函数不做范围检查, 调用者请确保它的值在范围内 (For performance purposes, this function does not do range checking; the caller should ensure that its value is within the range).

Returns

Vector128<T>: Returns bits mask mask (返回位集掩码).

Type Parameters

T: The vector element type (向量中的元素的类型).

Remarks

It performs better than GetMaskBits(int) when running net5+.
