Enum riscv::paging::MapToError

source · [−]

pub enum MapToError {
    FrameAllocationFailed,
    ParentEntryHugePage,
    PageAlreadyMapped,
}

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`

The given page is already mapped to a physical frame.
