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: u64, digest: Digest) -> ObjectReference

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) -> u64

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, ) -> ObjectReference

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, u64, Digest)

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