Struct mmtk::util::address::ObjectReference

#[repr(transparent)]pub struct ObjectReference(_);

ObjectReference represents address for an object. Compared with Address, operations allowed on ObjectReference are very limited. No address arithmetics are allowed for ObjectReference. The idea is from the paper High-level Low-level Programming (VEE09) and JikesRVM.

Implementations

impl ObjectReference

pub fn to_address(self) -> Address

converts the ObjectReference to an Address

pub fn is_null(self) -> bool

is this object reference null reference?

pub fn value(self) -> usize

returns the ObjectReference

pub fn is_live(self) -> bool

pub fn is_movable(self) -> bool

pub fn is_mapped(self) -> bool

Trait Implementations

impl Clone for ObjectReference

fn clone(&self) -> ObjectReference

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for ObjectReference

impl Debug for ObjectReference

allows Debug format the Address (as upper-case hex value with 0x prefix)

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

Formats the value using the given formatter.

impl Display for ObjectReference

allows Display format the Address (as upper-case hex value with 0x prefix)

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

Formats the value using the given formatter.

impl Eq for ObjectReference

impl Hash for ObjectReference

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

Feeds this value into the given Hasher.

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

Feeds a slice of this type into the given Hasher.

impl LowerHex for ObjectReference

allows print Address as lower-case hex value

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

Formats the value using the given formatter.

impl PartialEq<ObjectReference> for ObjectReference

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl PartialOrd<ObjectReference> for ObjectReference

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

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

#[must_use]pub fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]pub fn le(&self, other: &Rhs) -> bool

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

#[must_use]pub fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]pub fn ge(&self, other: &Rhs) -> bool

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

impl StructuralEq for ObjectReference

impl StructuralPartialEq for ObjectReference

impl UpperHex for ObjectReference
