Method: Webmachine::Streaming::IOEncoder#size

Defined in:

#size ⇒ Integer Also known as: bytesize

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Returns the length of the IO stream, if known. Returns nil if the stream uses an encoder or charsetter that might modify the length of the stream, or the stream size is unknown.
