It is possible that this will also allow parsing mach-o images which are mapped into a running process, inside that process's memory - if one makes a ReadRef implementation which only allows accessing mapped memory regions. But I haven't tried it, and maybe there are other offsets one needs to take into account in that use case. |

This allows parsing Mach-O images inside dyld shared cache files (gimli-rs#268): The dyld shared cache contains multiple images at different offsets; all these images share the same address space for absolute offsets such as symoff. Due to these absolute offsets, one cannot just parse the images by subsetting the input slice and parsing at header offset zero. This patch is a breaking change because it adds a header_offset argument to the MachHeader methods load_commands and uuid, and MachHeader is part of the public API.
