Enum riscv::paging::UnmapError

source · [−]

pub enum UnmapError<P: PhysicalAddress> {
    ParentEntryHugePage,
    PageNotMapped,
    InvalidFrameAddress(P),
}

Expand description

An error indicating that an unmap call failed.

Variants

`ParentEntryHugePage`

An upper level page table entry has the HUGE_PAGE flag set, which means that the given page is part of a huge page and can’t be freed individually.

`PageNotMapped`

The given page is not mapped to a physical frame.

`InvalidFrameAddress(P)`

The page table entry for the given page points to an invalid physical address.
