Extracted from #1399
Description
This PR adds a new
MarshalString
API:This allows marshalling an
HSTRING
to aReadOnlySpan<char>
value, without allocating a temporarystring
. The "Unsafe" suffix matches the naming convention in the BCL for methods that are not safe when misused. In this case, callers have to make sure not to escape the returnedReadOnlySpan<char>
value outside of the scope where theHSTRING
is valid.Developers can use this where appropriate, and we can also use this in eg. marshalling stubs in the future. Once we update the projections to require C# 11, we can also restore #1399 and leverage this API there as well.
