You might want to look at the text on that page: "stream trolls"?!

For what it's worth, there was/is a proposal to include what you called a
"memory stream" in Ada 202x. There's been one in Claw since it was created,
and I hear that it comes up frequently enough that it probably should be
standard.
The Claw version (Claw.Marshalling.Buffer_Type) uses a discriminanted type
so that the dangerous use of 'Address isn't necessary. It expands the buffer
when necessary, but I would expect that would get dropped from a Standard
version. And probably the names would get changed. But here's the spec:
package Claw.Marshalling is
type Buffer_Type(Initial_Length : Ada.Streams.Stream_Element_Count)
is new Ada.Streams.Root_Stream_Type with private;
procedure Read(
Stream : in out Buffer_Type;
Item : out Ada.Streams.Stream_Element_Array;
Last : out Ada.Streams.Stream_Element_Offset);
procedure Write(
Stream : in out Buffer_Type;
Item : in Ada.Streams.Stream_Element_Array);
function Length(Stream : in Buffer_Type)
return Ada.Streams.Stream_Element_Count;
-- Return the total length of data written into the buffer.
procedure Clear(Stream : in out Buffer_Type);
-- Empty the buffer.
private
....
