If required, throw a `TestInStreamException` (see `throwExceptionIfInputLimitExhausted`); otherwise, consume a string from this input stream, assign that value to the specified `variable`, update the cursor location, and return a reference to this stream. If this stream is initially invalid, this operation has no effect. If this function otherwise fails to extract a valid value, this stream is marked invalid and the value of `variable` is undefined. The string must be prefaced by a non‐negative integer indicating the number of characters composing the string. The behavior is undefined unless the length indicator is non‐negative.
