Implementations§

source§

impl GuestAddress

source

pub fn offset_from(self, base: GuestAddress) -> u64

Returns the offset from this address to the given base address.

§Examples
  let base = GuestAddress(0x100);
  let addr = GuestAddress(0x150);
  assert_eq!(addr.offset_from(base), 0x50u64);
source

pub fn offset(self) -> u64

Returns the address as a u64 offset from 0x0. Use this when a raw number is needed to pass to the kernel.

source

pub fn checked_add(self, other: u64) -> Option<GuestAddress>

Returns the result of the add or None if there is overflow.

source

pub fn unchecked_add(self, offset: u64) -> GuestAddress

Returns the result of the base address + the size. Only use this when offset is guaranteed not to overflow.

source

pub fn checked_sub(self, other: u64) -> Option<GuestAddress>

Returns the result of the subtraction of None if there is underflow.

source

pub fn mask(self, mask: u64) -> GuestAddress

Returns the bitwise and of the address with the given mask.

source

pub fn align(self, align: u64) -> Option<GuestAddress>

Returns the next highest address that is a multiple of align, or an unchanged copy of the address if it’s already a multiple of align. Returns None on overflow.

align must be a power of 2.
