Struct pallet_collection::Module

pub struct Module<T: Config>(_);

The module declaration.

Implementations

impl<T: Config + 'static> Module<T>

pub fn get_nonce() -> u128

Increment number used to create collection_id.

pub fn collections<K: EncodeLike<T::Hash>>(
    key: K
) -> CollectionInfo<T::AccountId>

The set of collection.

impl<T: Config> Module<T>

Can also be called using Call.

pub fn create_collection(
    origin: T::Origin,
    uri: Vec<u8>,
    is_fungible: bool
) -> DispatchResult

Create a new collection.

The dispatch origin of this call must be Signed.

Parameters:

• uri: Used to get the detailed information of the collection such as name, description, cover_image, which can be the CID of ipfs or a URL.
• is_fungible: Is FT or not.

NOTE: Calling this function will bypass origin filters.
