Struct CopyToWalker 

pub struct CopyToWalker<'a, PTE, Mapper, Error>
where
    PTE: FromPrimitive + PrimInt + Unsigned,
    Mapper: PageTableMapper<PTE, Error>,
{
    pub mapper: &'a mut Mapper,
    pub offset: usize,
    pub data: &'a [u8],
    pub format: &'a PageFormat<'a, PTE>,
    pub error: PhantomData<Error>,
}

The CopyToWalker struct is an implementation of a crate::walker::PageWalker used to copy data to a given a virtual address range.

This is used by the AddressSpace::copy_to method.

Fields

mapper: &'a mut Mapper

The page table mapper.

offset: usize

The offset within the buffer.

data: &'a [u8]

Storage for the data to copy.

format: &'a PageFormat<'a, PTE>

The page format.

error: PhantomData<Error>

A marker for Error.

Trait Implementations

impl<'a, PTE, Mapper, Error> PageWalker<PTE, Error> for CopyToWalker<'a, PTE, Mapper, Error>

where PTE: FromPrimitive + PrimInt + Unsigned, Mapper: PageTableMapper<PTE, Error>,

fn read_pte(&self, phys_addr: PTE) -> Result<PTE, Error>

Reads the PTE at the given physical address.

fn handle_pte( &mut self, pte_type: PteType, range: Range<usize>, pte: &PTE, ) -> Result<(), Error>

Maps the page and copies the data from the buffer.

fn handle_pte_hole( &mut self, _level: usize, _range: Range<usize>, _pte: &PTE, ) -> Result<(), Error>

This callback handles a PTE hole, i.e. a PTE that is not marked as present, and is given the level, the virtual address range and an immutable reference to the PTE. The implementation of this callback is optional.

fn handle_post_pte( &mut self, _level: usize, _range: Range<usize>, _pte: &PTE, ) -> Result<(), Error>

This callback handles the PTE of a page table after recursing the page table hierarchy, and is given the level, the virtual address and an immutable reference to the PTE. The implementation of this callback is optional.
