Struct cw721_base::Ownership

pub struct Ownership<T>where
    T: AddressLike,{
    pub owner: Option<T>,
    pub pending_owner: Option<T>,
    pub pending_expiry: Option<Expiration>,
}

The contract’s ownership info

Fields

owner: Option<T>

The contract’s current owner. None if the ownership has been renounced.

pending_owner: Option<T>

The account who has been proposed to take over the ownership. None if there isn’t a pending ownership transfer.

pending_expiry: Option<Expiration>

The deadline for the pending owner to accept the ownership. None if there isn’t a pending ownership transfer, or if a transfer exists and it doesn’t have a deadline.

Implementations

impl<T> Ownership<T>where T: AddressLike,

pub fn into_attributes(self) -> Vec<Attribute, Global>

Serializes the current ownership state as attributes which may be used in a message response. Serialization is done according to the std::fmt::Display implementation for T and cosmwasm_std::Expiration (for pending_expiry). If an ownership field has no value, "none" will be serialized.

Attribute keys used:

• owner
• pending_owner
• pending_expiry

Callers should take care not to use these keys elsewhere in their response as CosmWasm will override reused attribute keys.

Example

use cw_utils::Expiration;

assert_eq!(
    Ownership {
        owner: Some("blue"),
        pending_owner: None,
        pending_expiry: Some(Expiration::Never {})
    }
    .into_attributes(),
    vec![
        Attribute::new("owner", "blue"),
        Attribute::new("pending_owner", "none"),
        Attribute::new("pending_expiry", "expiration: never")
    ],
)

Trait Implementations

impl<T> Clone for Ownership<T>where T: Clone + AddressLike,

fn clone(&self) -> Ownership<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Ownership<T>where T: Debug + AddressLike,

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

Formats the value using the given formatter.

impl<'de, T> Deserialize<'de> for Ownership<T>where T: AddressLike + Deserialize<'de>,

fn deserialize<__D>( __deserializer: __D ) -> Result<Ownership<T>, <__D as Deserializer<'de>>::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> JsonSchema for Ownership<T>where T: AddressLike + JsonSchema,

fn schema_name() -> String

The name of the generated JSON Schema.

fn json_schema(gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl<T> PartialEq<Ownership<T>> for Ownership<T>where T: PartialEq<T> + AddressLike,

fn eq(&self, other: &Ownership<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T> Serialize for Ownership<T>where T: AddressLike + Serialize,

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<T> StructuralPartialEq for Ownership<T>where T: AddressLike,
