Methods

BinarySearch<T>(ReadOnlyUnmanagedSpan<T>, T)

Searches a sorted span for the specified value using binary search. Returns the index if found, or a negative number if not found. The negative number is the bitwise complement of the index where the value should be inserted.

public static long BinarySearch<T>(this ReadOnlyUnmanagedSpan<T> span, T value) where T : unmanaged, IComparable<T>

Parameters

span ReadOnlyUnmanagedSpan<T>

value T

Returns

long

Type Parameters

T

BinarySearch<T>(UnmanagedSpan<T>, T)

Searches a sorted span for the specified value using binary search. Returns the index if found, or a negative number if not found. The negative number is the bitwise complement of the index where the value should be inserted.

public static long BinarySearch<T>(this UnmanagedSpan<T> span, T value) where T : unmanaged, IComparable<T>

Parameters

span UnmanagedSpan<T>

value T

Returns

long

Type Parameters

T

Contains<T>(ReadOnlyUnmanagedSpan<T>, T)

Searches for the specified value and returns true if found. Uses SIMD acceleration for numeric types.
