Enum MapToError 

pub enum MapToError<S>
where
    S: PageSize,
{
    FrameAllocationFailed,
    ParentEntryHugePage,
    PageAlreadyMapped(PhysFrame<S>),
}
Expand description

This error is returned from map_to and similar methods.

Variants§

§

FrameAllocationFailed

An additional frame was needed for the mapping process, but the frame allocator returned None.

§

ParentEntryHugePage

An upper level page table entry has the HUGE_PAGE flag set, which means that the given page is part of an already mapped huge page.

§

PageAlreadyMapped(PhysFrame<S>)

The given page is already mapped to a physical frame.
