I've got this same challenge. The contents of any file within a zip needs
to be read as a stream, hence why there is no underlying seek method
available (assuming to handle the decompression properly) So if you want to
seek in a file within a zip, you need to read into a buffer first. You
don't h
Yea - my bad. Should be fine.

The function that was pointed to takes an ~io.ReadSeeker (oddly
Others have suggested passing a ByteBuffer - I don’t think that will work
because you will be missing other methods that are probably needed (FileInfo to
get the name, etc)

fs.FS does not support positional reads. It is always the entire file.
You can create a wrapper struct that implements the Seek() (trivial - just keep
a position and adjust Read() accordingly).

Would it be acceptable to conditionally copy the reader's contents into
a buffer tha
I have a program that needs to work equally for a directory of files or for the
contents of a zip file, so I'm using an fs.FS to abstract the two.
Some of the files need to be provided to a PDF importer that accepts an
io.ReadSeeker (#1).
Generally this is working fine except when trying to co
