Struct UID

pub struct UID {
    pub id: ID,
}

Globally unique IDs that define an object’s ID in storage. Any Sui Object, that is a struct with the key ability, must have id: UID as its first field. These are globally unique in the sense that no two values of type UID are ever equal, in other words for any two values id1: UID and id2: UID, id1 != id2. This is a privileged type that can only be derived from a TxContext. UID doesn’t have the drop ability, so deleting a UID requires a call to delete.

Fields

id: ID

Implementations

Trait Implementations

impl Clone for UID

fn clone(&self) -> UID

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UID

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for UID

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for UID

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

Formats the value using the given formatter.

impl From<ObjectId> for UID

fn from(value: ObjectId) -> Self

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 Hash for UID

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

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 MoveStruct for UID

type StructTag = UIDTypeTag

impl MoveType for UID

type TypeTag = UIDTypeTag

fn from_bcs(bytes: &[u8]) -> Result<Self, Error>

Deserialize the contents of the Move type from BCS bytes.

fn into_bcs(self) -> Result<Vec<u8>, Error>

Consuming version of to_bcs.

fn to_bcs(&self) -> Result<Vec<u8>, Error>

Serialize the contents of the Move type to BCS bytes.

fn into_json(self) -> Value

Consuming version of to_json.

fn to_json(&self) -> Value

Serialize the contents of the Move type to JSON.

impl PartialEq for UID

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StaticName for UID

fn name() -> Identifier

impl StaticTypeParams for UID

fn type_params() -> Vec<TypeTag>

impl Tabled for UID

const LENGTH: usize = 1usize

A length of fields and headers, which must be the same.

fn fields(&self) -> Vec<Cow<'_, str>>

Fields method must return a list of cells.

fn headers() -> Vec<Cow<'static, str>>

Headers must return a list of column names.
