Struct ObjectReference 

pub struct ObjectReference { /* private fields */ }

Reference to an object

Contains sufficient information to uniquely identify a specific object.

BCS

The BCS serialized form for this type is defined by the following ABNF:

object-ref = address u64 digest

Implementations

impl ObjectReference

pub fn new(object_id: Address, version: Version, digest: Digest) -> Self

Creates a new object reference from the object’s id, version, and digest.

pub fn object_id(&self) -> &Address

Returns a reference to the object id that this ObjectReference is referring to.

pub fn version(&self) -> Version

Returns the version of the object that this ObjectReference is referring to.

pub fn digest(&self) -> &Digest

Returns the digest of the object that this ObjectReference is referring to.

pub fn coin_reservation( coin_type: &StructTag, balance: u64, epoch: u64, chain_id: Digest, owner: Address, ) -> Self

Available on crate features hash and serde only.

Construct a synthetic coin reservation reference.

The reservation ref encodes an address-balance reservation for coin usage so that the server can reserve the specified balance of the sender’s address balance and transparently create a Coin<T> without requiring actual coin objects.

See the coin reservation protocol for the full specification.

pub fn into_parts(self) -> (Address, Version, Digest)

Returns a 3-tuple containing the object id, version, and digest.

Trait Implementations

impl Arbitrary for ObjectReference

type Parameters = ()

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = BoxedStrategy<ObjectReference>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(args: <Self as Arbitrary>::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for ObjectReference

fn clone(&self) -> ObjectReference

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ObjectReference

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ObjectReference

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ObjectReference

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

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ObjectReference
