Struct PageTableIndex 

pub struct PageTableIndex(u16);

A 9-bit index into a page table.

Can be used to select one of the 512 entries of a page table.

Guaranteed to only ever contain 0..512.

Tuple Fields

0: u16

Implementations

impl PageTableIndex

pub const fn new(index: u16) -> PageTableIndex

Creates a new index from the given u16. Panics if the given value is >=512.

pub const fn new_truncate(index: u16) -> PageTableIndex

Creates a new index from the given u16. Throws away bits if the value is >=512.
