Struct libafl_bolts::shmem::unix_shmem::MmapShMem

pub struct MmapShMem { /* private fields */ }

Mmap ShMem for Unix Mmap-based The sharedmap impl for unix using shm_open and mmap. Default on MacOS and iOS, where we need a central point to unmap shared mem segments for dubious Mach kernel reasons.
