Module concordium_base::cis2_types

This module contains types and their implementations related to the CIS-2 token standard.

Structs

• AdditionalData
  Additional data which can be included for each transfer in the transfer parameter for the CIS2 contract function transfer. Allows up to u16::MAX number of bytes.
• BalanceOfQuery
  A query for the balance of a given address for a given token.
• BalanceOfQueryParams
  The parameter type for the NFT contract function CIS2-NFT.balanceOf.
• BalanceOfQueryResponse
  The response which is sent back when calling the contract function balanceOf. It consists of the list of token amounts in the same order as the queries.
• MetadataUrl
  A URL for the metadata.
• NewAdditionalDataError
  Error for constructing a new AdditionalData.
• NewBalanceOfQueryParamsError
  Error for constructing a new BalanceOfQueryParams.
• NewBalanceOfQueryResponseError
  Error for constructing a new BalanceOfQueryResponse.
• NewMetadataUrlError
  Error for constructing a new MetadataUrl.
• NewOperatorOfQueryParamsError
  Error for constructing a new OperatorOfQueryParams.
• NewOperatorOfQueryResponseError
  Error for constructing a new OperatorOfQueryResponse.
• NewTokenIdError
  Error for constructing a new TokenId.
• NewTokenMetadataQueryParamsError
  Error for constructing a new TokenMetadataQueryParams.
• NewTokenMetadataQueryResponseError
  Error for constructing a new TokenMetadataQueryResponse.
• NewTransferParamsError
  Error for constructing a new TransferParams.
• NewUpdateOperatorParamsError
  Error for constructing a new UpdateOperatorParams.
• OperatorOfQuery
  A query for the operator of a given address for a given token.
• OperatorOfQueryParams
  The parameter type for the NFT contract function CIS2-NFT.operatorOf.
• OperatorOfQueryResponse
  The response which is sent back when calling the contract function operatorOf. It consists of the list of results in the same order and length as the queries in the parameter.
• TokenAddress
  Full address of a token.
• TokenAmount
  CIS-2 token amount with serialization as according to CIS-2.
• TokenId
  CIS2 Token ID can be up to 255 bytes in size.
• TokenMetadataQueryParams
  The parameter type for the NFT contract function CIS2-NFT.operatorOf.
• TokenMetadataQueryResponse
  The response which is sent back when calling the contract function tokenMetadata. It consists of the list of queries paired with their corresponding result.
• Transfer
  A description of a transfer according to the CIS2 specification.
• TransferParams
  The parameter type for the NFT contract function CIS2-NFT.transfer.
• UpdateOperator
• UpdateOperatorParams
  The parameter type for the NFT contract function CIS2-NFT.updateOperator.

Enums

• Cis2ErrorRejectReason
  The different errors found in CIS2.
• Event
  Smart contract logged event, part of the CIS2 specification.
• FromStrAdditionalDataError
  Error for constructing a AdditionalData from a string.
• OperatorUpdate
  The type of update for an operator update.
• ParseTokenAddressError
• ParseTokenIdVecError
  Error from parsing a token ID bytes from a hex encoded string.
• Receiver
  Address to receive an amount of tokens, it differs from the Address type by additionally requiring a contract receive function name when the address is a contract address.

Type Aliases

• TokenMetadataQuery
  A query for token metadata for a given token.
