Struct NFTManager 

pub struct NFTManager { /* private fields */ }

A highly optimized library for managing NFTs (Non-Fungible Tokens) in Ethereum-compatible WebAssembly (WASM).

Implementations

impl NFTManager

pub fn new(owner: &str) -> NFTManager

Initialize a new NFTManager

pub fn create_class( &mut self, class_id: &str, metadata: &str, caller: &str, ) -> Result<(), String>

Create a new NFT class. Only the contract owner can create classes.

pub fn mint( &mut self, class_id: &str, token_id: &str, metadata: &str, caller: &str, ) -> Result<(), String>

Mint a new token within an NFT class. Only the owner of the class can mint.

pub fn transfer( &mut self, token_id: &str, new_owner: &str, caller: &str, ) -> Result<(), String>

Transfer a token to another owner. Must be the token owner or approved operator.

pub fn approve( &mut self, token_id: &str, approved: &str, caller: &str, ) -> Result<(), String>

Approve another account to transfer the given token.

pub fn burn(&mut self, token_id: &str, caller: &str) -> Result<(), String>

Burn a token (remove it from circulation). Only the token owner can burn the token.

pub fn get_owner(&self, token_id: &str) -> Result<String, String>

Check the owner of a token.

pub fn is_approved(&self, token_id: &str, operator: &str) -> bool

Check if an address is approved for the given token.

pub fn transfer_ownership( &mut self, new_owner: &str, caller: &str, ) -> Result<(), String>

Set a new owner for the NFTManager contract.

Trait Implementations

impl From<NFTManager> for JsValue

fn from(value: NFTManager) -> Self

Converts to this type from the input type.

impl FromWasmAbi for NFTManager

type Abi = WasmPtr<WasmRefCell<NFTManager>>

The Wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: Self::Abi) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for NFTManager

type Abi = WasmPtr<WasmRefCell<NFTManager>>

The Wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> Self::Abi

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl LongRefFromWasmAbi for NFTManager

type Abi = WasmPtr<WasmRefCell<NFTManager>>

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<NFTManager>

Same as RefFromWasmAbi::Anchor

unsafe fn long_ref_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for NFTManager

fn is_none(abi: &Self::Abi) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for NFTManager

fn none() -> Self::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl RefFromWasmAbi for NFTManager

type Abi = WasmPtr<WasmRefCell<NFTManager>>

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<NFTManager>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.

unsafe fn ref_from_abi(js: Self::Abi) -> Self::Anchor

Recover a Self::Anchor from Self::Abi.

impl RefMutFromWasmAbi for NFTManager

type Abi = WasmPtr<WasmRefCell<NFTManager>>

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<NFTManager>

Same as RefFromWasmAbi::Anchor

unsafe fn ref_mut_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl SupportsConstructor for NFTManager

impl SupportsInstanceProperty for NFTManager

impl SupportsStaticProperty for NFTManager

impl TryFromJsValue for NFTManager

fn try_from_js_value(value: JsValue) -> Result<Self, JsValue>

Performs the conversion.

fn try_from_js_value_ref(value: &JsValue) -> Option<Self>

Performs the conversion.

impl VectorFromWasmAbi for NFTManager

type Abi = <Box<[JsValue]> as FromWasmAbi>::Abi

unsafe fn vector_from_abi(js: Self::Abi) -> Box<[NFTManager]>

impl VectorIntoWasmAbi for NFTManager

type Abi = <Box<[JsValue]> as IntoWasmAbi>::Abi

fn vector_into_abi(vector: Box<[NFTManager]>) -> Self::Abi

impl WasmDescribe for NFTManager

fn describe()

impl WasmDescribeVector for NFTManager

fn describe_vector()
