impl Mapper for Mapper

fn map( &self, mem_offset: u64, size: usize, fd: &dyn AsRawFd, file_offset: u64, prot: Protection, ) -> Result<()>

Maps size bytes starting at file_offset bytes from within the given fd at mem_offset bytes from the start of the memory region with prot protections. mem_offset must be page aligned.

fn unmap(&self, offset: u64, size: u64) -> Result<()>

Unmaps size bytes at offset bytes from the start of the memory region. offset must be page aligned.
