Overview

Read-state accumulator. The libpng read callback reads PNG bytes out of this; the offset advances with each call. Wrapping the state in a small struct keeps the FFI::Function closure capture explicit (and the closure itself becomes trivially shareable because the struct's instance vars are not mutated outside the callback).

Instance Attribute Summary
