Create a t with the given contents

Create a t that can be fed bytes continually using feed_exn.

total_bytes will be fed through to the Progress value in any reads. Note that we do nothing smart to close t when you have fed at least total_bytes bytes to t.

If t was created using create_stream, you can feed it more bytes. Raises if t was created using create_static, or if close or close_error have been called.

Mark t as closed so that any file reads based on t will be marked complete. close is idempotent and does nothing if t was created using create_static.

Close t with an error to emulate an error when reading from the file. Does nothing if close has already been called or t was created using create_static.

Describes whether a read is currently ongoing for the stream in question.
