Trait MemoryMapper 

pub trait MemoryMapper {
    // Required methods
    fn remap_range(
        &self,
        range: &Range<usize>,
        set: u64,
        clr: u64,
    ) -> Result<(), &str>;
    fn query_range(&self, range: &Range<usize>) -> Option<u64>;
}

An implementation of this trait must be provided to the EFI runtime at initialization time so that the PE/COFF loader as well as the Memory Attributes Protocol implementation exposed by the EFI runtime are able to manage permission attributes on memory ranges.

Example

struct MemoryMapper;
impl efiloader::MemoryMapper for MemoryMapper {
    fn remap_range(&self, range: &Range<usize>, set: u64, clr: u64) -> Result<(), &str> {
        let prot = libc::PROT_READ
            | match clr & !set {
                EFI_MEMORY_RO => libc::PROT_WRITE,
                EFI_MEMORY_XP => libc::PROT_EXEC,
                0 => 0,
                _ => libc::PROT_WRITE | libc::PROT_EXEC,
            };

        unsafe { libc::mprotect(range.start as *mut _, range.end - range.start, prot) };
        Ok(())
    }

    fn query_range(&self, _range: &Range<usize>) -> Option<u64> {
        todo!();
    }
}

Required Methods
