Struct ERC1155

pub struct ERC1155 { /* private fields */ }

A highly optimized ERC1155 implementation in Rust for WebAssembly (WASM).

Implementations

impl ERC1155

pub fn new(owner: &str) -> ERC1155

Initializes a new ERC1155 contract with the owner.

Parameters

• owner: The initial owner of the contract.

pub fn mint( &mut self, caller: &str, token_id: u32, amount: u64, ) -> Result<(), String>

Mints new tokens for a given token_id (only admins can mint).

Parameters

• caller: The address calling the function (must be an admin).
• token_id: The ID of the token to mint.
• amount: The number of tokens to mint.

pub fn transfer( &mut self, caller: &str, to: &str, token_id: u32, amount: u64, ) -> Result<(), String>

Transfers tokens to another user.

Parameters

• caller: The address initiating the transfer (must be owner or approved).
• to: The recipient of the tokens.
• token_id: The ID of the token being transferred.
• amount: The number of tokens to transfer.

pub fn approve( &mut self, caller: &str, approved: &str, token_id: u32, ) -> Result<(), String>

Approves another user to transfer tokens on behalf of the caller.

pub fn balance_of(&self, owner: &str, token_id: u32) -> u64

Returns the balance of tokens for a specific user and token ID.

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

Adds a new admin to the contract (only the owner can add admins).

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

Transfers ownership of the contract (only the current owner can transfer).

Trait Implementations

impl From<ERC1155> for JsValue

fn from(value: ERC1155) -> Self

Converts to this type from the input type.

impl FromWasmAbi for ERC1155

type Abi = u32

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

unsafe fn from_abi(js: u32) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for ERC1155

type Abi = u32

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

fn into_abi(self) -> u32

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

impl LongRefFromWasmAbi for ERC1155

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<ERC1155>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for ERC1155

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 ERC1155

fn none() -> Self::Abi

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

impl RefFromWasmAbi for ERC1155

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<ERC1155>

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 ERC1155

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<ERC1155>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for ERC1155

type Error = JsValue

The type returned in the event of a conversion error.

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

Performs the conversion.

impl VectorFromWasmAbi for ERC1155

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

unsafe fn vector_from_abi(js: Self::Abi) -> Box<[ERC1155]>

impl VectorIntoJsValue for ERC1155

fn vector_into_jsvalue(vector: Box<[ERC1155]>) -> JsValue

impl VectorIntoWasmAbi for ERC1155

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

fn vector_into_abi(vector: Box<[ERC1155]>) -> Self::Abi
