Implementations

impl<T: Config + 'static> Module<T>

pub fn next_nft_order_id() -> u128

Next order_id.

pub fn nft_order<K: EncodeLike<u128>>(
    key: K
) -> NonFungibleOrderInfo<T::Hash, T::AccountId, <<T as Config>::Currency as Currency<<T as Config>::AccountId>>::Balance>

The set of NFT orders. order_id => (collection_id, token_id)

pub fn semi_fungible_pool<K: EncodeLike<(T::Hash, T::AccountId)>>(
    key: K
) -> SemiFungiblePoolInfo<T::AccountId, <<T as Config>::Currency as Currency<<T as Config>::AccountId>>::Balance, T::BlockNumber>

impl<T: Config> Module<T>

Can also be called using Call.

pub fn sell_nft(
    origin: T::Origin,
    collection_id: T::Hash,
    token_id: u128,
    amount: u128,
    price: <<T as Config>::Currency as Currency<<T as Config>::AccountId>>::Balance
) -> DispatchResult

Sell one or a batch of NFTs.

The dispatch origin of this call must be Signed.

Parameters:

• collection_id: The collection_id of the NFT to be sold.
• token_id: The index of the NFT to be sold.
• amount: How many NFTs to sell.
• price: Pricing of NFTs.

NOTE: Calling this function will bypass origin filters.

pub fn buy_nft(
    origin: T::Origin,
    order_id: u128,
    amount: u128
) -> DispatchResult

Buy one or a batch of NFTs.

The dispatch origin of this call must be Signed.

Parameters:

• order_id: The id of the order
• amount: How many NFTs to buy.

NOTE: Calling this function will bypass origin filters.

pub fn cancel_nft_order(origin: T::Origin, order_id: u128) -> DispatchResult

Cancel the order and get back the NFTs locked in the pallet.

The dispatch origin of this call must be Signed.

Parameters:

• order_id: Order to cancel.

NOTE: Calling this function will bypass origin filters.

pub fn create_semi_token_pool(
    origin: T::Origin,
    collection_id: T::Hash,
    amount: u128,
    reverse_ratio: u128,
    m: u128,
    duration: T::BlockNumber
) -> DispatchResult

Create a pool.

Because the Bancor formula cannot be used when the assets in the pool are zero, you need to use m to calculate the price of the first purchase.

The dispatch origin of this call must be Signed.

Parameters:

• collection_id: The collection where FT is located.
• amount: How many FTs to sell.
• reverse_ratio: Value that affects price sensitivity.
• duration: The duration of the pool.

NOTE: Calling this function will bypass origin filters.

pub fn buy_semi_token(
    origin: T::Origin,
    collection_id: T::Hash,
    seller: T::AccountId,
    amount: u128
) -> DispatchResult

Buy FTs from pool.

The dispatch origin of this call must be Signed.

Parameters:

• collection_id: The collection where FT is located.
• seller: The creator of the pool.
• amount: How many NFTs to buy.

NOTE: Calling this function will bypass origin filters.

pub fn sell_semi_token(
    origin: T::Origin,
    collection_id: T::Hash,
    seller: T::AccountId,
    amount: u128
) -> DispatchResult

Sell FTs to pool.

The dispatch origin of this call must be Signed.

Parameters:

• collection_id: The collection where FT is located.
• seller: The creator of the pool.
• amount: How many NFTs to sell.

NOTE: Calling this function will bypass origin filters.

pub fn withdraw_pool(
    origin: T::Origin,
    collection_id: T::Hash
) -> DispatchResult

Withdraw assets from the pool by creator.

The dispatch origin of this call must be Signed.

Parameters:

• collection_id: The collection where FT is located.

NOTE: Calling this function will bypass origin filters.
