[ExtensionAttribute]
static MemoryExtensions.SplitEnumerable Split(
	ReadOnlySpan<wchar_t> value, 
	ReadOnlySpan<wchar_t> separator, 
	StringSplitOptions options = StringSplitOptions::None
)

Parameters

value  ReadOnlySpan<Char>

The span to split.

separator  ReadOnlySpan<Char>

The separator that delimits the span segments.

options  StringSplitOptions  (Optional)

A bitwise combination of the enumeration values that specifies whether to trim substrings and include empty substrings.

Return Value

Usage Note

This method is similar to Split(String, StringSplitOptions), but operates on spans. It allows you to split a span into segments, and iterate the segments using a foreach loop, without allocating any memory.

Because the returned object is a ref struct, it implements the enumerable pattern, but does not implement the IEnumerable<T> interface. This means that while it can be used with foreach, it cannot be used with LINQ methods or other places that expect an IEnumerable<T>.
