Enum TranslateResult

Source
pub enum TranslateResult {
    Mapped {
        frame: MappedFrame,
        offset: u64,
        flags: PageTableFlags,
    },
    NotMapped,
    InvalidFrameAddress(PhysAddr),
}
Expand description

The return value of the Translate::translate function.

If the given address has a valid mapping, a Frame4KiB, Frame2MiB, or Frame1GiB variant is returned, depending on the size of the mapped page. The remaining variants indicate errors.

Variants§

§

Mapped

The virtual address is mapped to a physical frame.

Fields

§frame: MappedFrame

The mapped frame.

§offset: u64

The offset within the mapped frame.

§flags: PageTableFlags

The entry flags in the lowest-level page table.

Flags of higher-level page table entries are not included here, but they can still affect the effective flags for an address, for example when the WRITABLE flag is not set for a level 3 entry.

§

NotMapped

The given virtual address is not mapped to a physical frame.

§

InvalidFrameAddress(PhysAddr)

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