If all you have in the file are functions, try enabling
outline-minor-mode, and customizing the buffer-local variable
outline-regexp to match your function name.  The idea is that you'd
match the function signature as a top-level outline header.

Maybe something like:

(setq outline-regexp "Function [a-z]+(.*):.*;$")

Then, try M-x hide-subtree on the function name line, and it will hide
the text between that line and the next function.
