Struct ObjectInner 

pub struct ObjectInner {
    pub data: ObjectData,
    pub owner: Owner,
    pub previous_transaction: Digest,
    pub storage_rebate: u64,
}

An object on the IOTA blockchain

BCS

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

object = object-data owner digest u64

Fields

data: ObjectData

The meat of the object

owner: Owner

The owner that unlocks this object

previous_transaction: Digest

The digest of the transaction that created or last mutated this object

storage_rebate: u64

The amount of IOTA we would rebate if this object gets deleted. This number is re-calculated each time the object is mutated based on the present storage gas price.

Implementations

impl Object

pub fn digest(&self) -> Digest

Calculate the digest of this Object

This is done by hashing the BCS bytes of this Object prefixed with a salt.

impl Object

pub fn new( data: ObjectData, owner: Owner, previous_transaction: Digest, storage_rebate: u64, ) -> Object

Build an object

pub fn id(&self) -> ObjectId

Return this object’s id

pub fn object_ref(&self) -> ObjectReference

Return this object’s reference

pub fn version(&self) -> Version

Return this object’s version

pub fn object_type(&self) -> ObjectType

Return this object’s type

pub fn as_struct_opt(&self) -> Option<&MoveStruct>

Try to interpret this object as a move struct

pub fn as_struct(&self) -> &MoveStruct

Interpret this object as a move struct

pub fn as_package_opt(&self) -> Option<&MovePackage>

Try to interpret this object as a move package

pub fn as_package(&self) -> &MovePackage

Interpret this object as a move package

pub fn owner(&self) -> &Owner

Return this object’s owner

pub fn data(&self) -> &ObjectData

Return this object’s data

pub fn previous_transaction(&self) -> Digest

Return the digest of the transaction that last modified this object

pub fn storage_rebate(&self) -> u64

Return the storage rebate locked in this object

Storage rebates are credited to the gas coin used in a transaction that deletes this object.

pub fn to_rust<'de, T>(&'de self) -> Result<T, Box<dyn Error + Send + Sync>>

where T: Deserialize<'de>,

pub fn is_immutable(&self) -> bool

Returns true if the object is immutable.

pub fn is_address_owned(&self) -> bool

Returns true if the object is owned by an address.

pub fn is_child_object(&self) -> bool

Returns true if the object is owned by another object.

pub fn is_shared(&self) -> bool

Returns true if the object is shared.

pub fn is_package(&self) -> bool

Returns true if this object is a Move package rather than a Move value.

pub fn is_system_package(&self) -> bool

Returns true if the object is a system package.

pub fn struct_tag(&self) -> Option<StructTag>

Returns the struct tag of this object if it is a Move struct.

pub fn is_gas_coin(&self) -> bool

Returns true if this object is a gas coin.

pub fn coin_type_opt(&self) -> Option<&TypeTag>

Returns the coin’s type parameter if this object is a coin.

pub fn single_owner(&self) -> Option<Address>

Returns the address of the single owner of this object (address- or object-owned), or None if it is shared or immutable.

pub fn set_owner(&mut self, new_owner: Address)

Sets the owner of this object to new_owner.

Trait Implementations

impl Arbitrary for Object

type Parameters = ()

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

type Strategy = BoxedStrategy<Object>

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

fn arbitrary_with( args_shared: <Object as Arbitrary>::Parameters, ) -> <Object as Arbitrary>::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 Object

fn clone(&self) -> Object

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Object

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Object

fn deserialize<__D>( __deserializer: __D, ) -> Result<Object, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Object> for Object

fn from(inner: ObjectInner) -> Self

Converts to this type from the input type.

impl Hash for Object

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

where __H: Hasher,

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 PartialEq for Object

fn eq(&self, other: &Object) -> 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 Object

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<Object> for Object

type Error = SdkTypeConversionError

The type returned in the event of a conversion error.

fn try_from(value: Object) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for Object

impl StructuralPartialEq for Object
