Struct PfsFileImage 

pub struct PfsFileImage<'a> { /* private fields */ }

A file within a PFS, exposed as an Image for chaining.

This adapter maps logical file offsets through the inode’s precomputed block map to physical offsets in the underlying PFS image. It is used to open nested PFS images (e.g. pfs_image.dat inside an outer PFS), optionally wrapped in PfscImage for decompression.

Created via File::into_image().
