pub(super) struct GuestOffset(pub u64);

Guest offset.

Tuple Fields

0: u64

Implementations

impl GuestOffset

pub fn in_cluster_offset(self, cluster_bits: u32) -> usize

Return the offset from the start of the containing guest clusters.

pub fn l2_index(self, cluster_bits: u32) -> usize

Return the containing cluster’s index in its L2 table.

pub fn l1_index(self, cluster_bits: u32) -> usize

Return the containing cluster’s L2 table’s index in the L1 table.

pub fn cluster(self, cluster_bits: u32) -> GuestCluster

Return the containing cluster’s index.

pub fn checked_cluster(self, cluster_bits: u32) -> Option<GuestCluster>

If this offset points to the start of a cluster, get its index.

If this offset points inside of a cluster, return None. As oposed to just cluster(), this will not discard information: self.checked_cluster(cb).unwrap().offset() == self, because there is no in-cluster offset that could be lost.

pub fn remaining_in_cluster(self, cluster_bits: u32) -> u64

How many bytes remain in this cluster after this offset.

pub fn remaining_in_l2_table(self, cluster_bits: u32) -> u64

How many bytes remain in this L2 table after this offset.

Trait Implementations

impl Add<u64> for GuestOffset

type Output = GuestOffset

The resulting type after applying the + operator.

fn add(self, rhs: u64) -> Self

Performs the + operation.

impl Clone for GuestOffset

fn clone(&self) -> GuestOffset

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GuestOffset

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for GuestOffset

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for GuestOffset

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for GuestOffset

fn cmp(&self, other: &GuestOffset) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for GuestOffset

fn eq(&self, other: &GuestOffset) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for GuestOffset

fn partial_cmp(&self, other: &GuestOffset) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Sub for GuestOffset

type Output = u64

The resulting type after applying the - operator.

fn sub(self, rhs: Self) -> u64
