Overloads

IndexOf(ReadOnlySpan<Char>, ReadOnlySpan<Char>, StringComparison)

Reports the zero-based index of the first occurrence of the specified value in the current span.

IndexOf<T>(Span<T>, T)

Searches for the specified value and returns the index of its first occurrence. Values are compared using IEquatable{T}.Equals(T).

IndexOf<T>(Span<T>, ReadOnlySpan<T>)

Searches for the specified sequence and returns the index of its first occurrence. Values are compared using IEquatable{T}.Equals(T).

IndexOf<T>(ReadOnlySpan<T>, T)

Searches for the specified value and returns the index of its first occurrence. Values are compared using IEquatable{T}.Equals(T).

IndexOf<T>(ReadOnlySpan<T>, ReadOnlySpan<T>)

Searches for the specified sequence and returns the index of its first occurrence. Values are compared using IEquatable{T}.Equals(T).

IndexOf(ReadOnlySpan<Char>, ReadOnlySpan<Char>, StringComparison)

Reports the zero-based index of the first occurrence of the specified value in the current span.
