Struct PageOffset 

pub struct PageOffset(/* private fields */);

A 12-bit offset into a 4KiB Page.

This type is returned by the VirtAddr::page_offset method.

Guaranteed to only ever contain 0..4096.

Implementations

impl PageOffset

pub fn new(offset: u16) -> Self

Creates a new offset from the given u16. Panics if the passed value is >=4096.

pub const fn new_truncate(offset: u16) -> Self

Creates a new offset from the given u16. Throws away bits if the value is >=4096.
