Struct VirtualAddressSpaceLayout 

pub struct VirtualAddressSpaceLayout { /* private fields */ }

Platform-owned page-table virtual-address layout.

Direct-map windows that bypass the page-table walker are deliberately not part of kernel. An empty user range means that the current build does not expose a user page table even if the architecture could support one.

Implementations

impl VirtualAddressSpaceLayout

pub fn try_new( user: Range<usize>, kernel: Range<usize>, ) -> Result<Self, VirtualAddressSpaceError>

Validates and constructs a platform layout.

pub fn user(&self) -> Range<usize>

Returns the lower range available to a user page table.

pub fn kernel(&self) -> Range<usize>

Returns the page-table-backed kernel allocation range.
