This API is not CLS-compliant.

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: Object
SpanMarshaller<T,TUnmanagedElement>

Attributes: CLSCompliantAttribute ContiguousCollectionMarshallerAttribute CustomMarshallerAttribute

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)	Allocates the space to store the unmanaged elements.
Free(TUnmanagedElement*)	Frees the allocated unmanaged memory.
GetManagedValuesDestination(Span<T>)	Gets a span of the space where the managed collection elements should be stored.
GetManagedValuesSource(Span<T>)	Gets a span of the managed collection elements.
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.
