Important

This API is not CLS-compliant.

Supports marshalling a ReadOnlySpan from managed value to a contiguous native array of the unmanaged values of the elements.

Type Parameters

T

The managed element type of the span.

TUnmanagedElement

The unmanaged type for the elements of the span.

Remarks

A ReadOnlySpan marshalled with this marshaller will match the semantics of GetReference(ReadOnlySpan). 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.
