Returns a Span<T> to write to that is at least the requested size (specified by sizeHint).

public Span<T> GetSpan (int sizeHint = 0);

abstract member GetSpan : int -> Span<'T>

Public Function GetSpan (Optional sizeHint As Integer = 0) As Span(Of T)

Parameters

sizeHint: Int32

The minimum length of the returned Span<T>. If 0, a non-empty buffer is returned.

Returns

Span<T>

A Span<T> of at least the size sizeHint. If sizeHint is 0, returns a non-empty buffer.

Remarks

There is no guarantee that successive calls will return the same buffer or the same-sized buffer.

This method must never return Span<T>.Empty, but it can throw if the requested buffer size is not available.

You must request a new buffer after calling Advance to continue writing more data; you cannot write to a previously acquired buffer.
