Struct dao::core_contracts::DaoNftRef

pub struct DaoNftRef { /* private fields */ }

Reference to the DaoNft contract instance.

Implementations

impl DaoNftRef

pub fn at(address: &Address) -> Self

pub fn address(&self) -> &Address

pub fn with_tokens<T>(&self, amount: T) -> Self

where T: Into<Balance>,

impl DaoNftRef

pub fn init(&mut self, name: String, symbol: String, base_uri: TokenUri)

Module constructor.

Initializes modules. Sets the deployer as the owner.

See Erc721MetadataExtension, AccessControl

pub fn total_supply(&self) -> Balance

Returns the total number of tokens.

pub fn token_id(&self, address: Address) -> Option<TokenId>

Returns the token id for a given address.

If the owner does not own any token the None value is returned.

pub fn token_uri(&self, token_id: TokenId) -> TokenUri

Returns a distinct Uniform Resource Identifier (URI) for a given asset.

pub fn mint(&mut self, to: Address)

Creates a new token with the next id and transfers it to a new owner. Increments the total supply and the balance of the to address.

Note

Only whitelisted addresses are permitted to call this function.

Each user is entitled to own only one token.

Errors

• UserAlreadyOwnsToken if the to address already owns a token.

Events

• [Transfer] event when minted successfully.

pub fn burn(&mut self, owner: Address)

Burns a token with the given id. Decrements the balance of the token owner and decrements the total supply.

Errors

• NotWhitelisted if the caller is not whitelisted.

Events

• [Transfer] event when burnt successfully.

pub fn propose_new_owner(&mut self, owner: Address)

Changes the ownership of the contract. Transfers ownership to the owner. Only the current owner is permitted to call this method.

pub fn accept_new_owner(&mut self)

Accepts the new owner proposition. This can be called only by the proposed owner.

pub fn add_to_whitelist(&mut self, address: Address)

Adds a new address to the whitelist.

pub fn remove_from_whitelist(&mut self, address: Address)

Remove address from the whitelist.

pub fn is_whitelisted(&self, address: Address) -> bool

Checks whether the given address is added to the whitelist. .

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

Returns the address of the current owner. .

pub fn name(&self) -> String

Returns a descriptive name for a collection of tokens in this contract.

pub fn symbol(&self) -> String

Gets an abbreviated name for tokens in this contract.

pub fn base_uri(&self) -> TokenUri

Returns a URI prefix that is used by all the assets.

pub fn owner_of(&self, token_id: &TokenId) -> Address

Returns the address of the owner of the token.

If the given token_id does not exist the None value is returned.

pub fn balance_of(&self, owner: &Address) -> U256

Returns the number of tokens owned by owner.

Trait Implementations

impl Clone for DaoNftRef

fn clone(&self) -> DaoNftRef

Returns a copy of the value.

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

Performs copy-assignment from source.
