Struct ObjectId

pub struct ObjectId(/* private fields */);

An ObjectId is a 32-byte identifier used to uniquely identify an object on the Sui blockchain.

Relationship to Address

Addresses and ObjectIds share the same 32-byte addressable space but are derived leveraging different domain-separator values to ensure, cryptographically, that there won’t be any overlap, e.g. there can’t be a valid Object whose ObjectId is equal to that of the Address of a user account.

BCS

An ObjectId’s BCS serialized form is defined by the following:

object-id = 32*OCTET

Implementations

impl ObjectId

pub const LENGTH: usize = 32usize

pub const ZERO: ObjectId

pub const fn new(bytes: [u8; 32]) -> ObjectId

Generates a new ObjectId from the provided byte array.

pub const fn into_inner(self) -> [u8; 32]

Returns the underlying byte array of an ObjectId.

pub const fn inner(&self) -> &[u8; 32]

Returns a reference to the underlying byte array of an ObjectId.

pub const fn as_bytes(&self) -> &[u8]

Returns a slice of bytes of an ObjectId.

pub const fn as_address(&self) -> &Address

Returns the underlying Address of an ObjectId.

Trait Implementations

impl From<[u8; 32]> for ObjectId

fn from(object_id: [u8; 32]) -> ObjectId

Converts to this type from the input type.

fn from(value: Address) -> ObjectId

Converts to this type from the input type.

impl From<ID> for ObjectId

fn from(value: ID) -> Self

Converts to this type from the input type.

impl From<ObjectId> for Address

fn from(value: ObjectId) -> Address

Converts to this type from the input type.

impl From<ObjectId> for ID

fn from(value: ObjectId) -> Self

Converts to this type from the input type.

impl From<ObjectId> for UID

fn from(value: ObjectId) -> Self

Converts to this type from the input type.

impl From<ObjectId> for Vec<u8>

fn from(value: ObjectId) -> Vec<u8>

Converts to this type from the input type.

impl From<UID> for ObjectId

fn from(value: UID) -> Self

Converts to this type from the input type.

impl FromStr for ObjectId

type Err = AddressParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<ObjectId, <ObjectId as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for ObjectId

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 Ord for ObjectId

fn cmp(&self, other: &ObjectId) -> 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,

impl PartialEq for ObjectId

fn eq(&self, other: &ObjectId) -> 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.

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.

where __S: Serializer,
