Supports marshalling a Span<T> from managed value to a contiguous native array of the unmanaged values of the elements.

Public Class SpanMarshaller(Of T, TUnmanagedElement)
Type Parameters
- T
The managed element type of the span.
- TUnmanagedElement
The unmanaged type for the elements of the span.
- Inheritance
-
SpanMarshaller<T,TUnmanagedElement>
- Attributes
Remarks
A Span<T> marshalled with this marshaller will match the semantics of GetReference<T>(Span<T>).
In particular, this marshaller will pass a non-null
value for a zero-length span if the span was constructed with a non-null
value.
Methods
AllocateContainerForManagedElements(TUnmanagedElement*, Int32) |
Allocates space to store the managed elements. |
AllocateContainerForUnmanagedElements(Span<T>, Int32) |

GetUnmanagedValuesDestination(TUnmanagedElement*, Int32) |
Gets a span of the space where the unmanaged collection elements should be stored. |
GetUnmanagedValuesSource(TUnmanagedElement*, Int32) |
Gets a span of the native collection elements. |
