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

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.
