Functions

func GetArweaveDataHTTP

func GetArweaveDataHTTP(ctx context.Context, id string) ([]byte, error)

func GetArweaveDataHTTPReader

func GetArweaveDataHTTPReader(ctx context.Context, id string) (io.ReadCloser, error)

func GetBalanceOfERC1155Token

func GetBalanceOfERC1155Token(ctx context.Context, pOwnerAddress, pContractAddress persist.EthereumAddress, pTokenID persist.HexTokenID, ethClient *ethclient.Client) (*big.Int, error)

GetBalanceOfERC1155Token returns the balance of an ERC1155 token

func GetDataFromURIAsReader

func GetDataFromURIAsReader(ctx context.Context, turi persist.TokenURI, mediaType persist.MediaType, ipfsClient *shell.Shell, arweaveClient *goar.Client, bufSize int, retrieveTimeout time.Duration, recurseRawReturns bool) (*util.FileHeaderReader, persist.MediaType, error)

GetDataFromURIAsReader calls URI and returns the data as an unread reader with the headers pre-read. retrieveTimeout is the timeout for just the retrieval of the reader, not the reading of the reader which will be handled by the context recurseRawReturns will cause the function to recursively call itself if the reader returned from any initial call is a "raw" URI (a URI that in itself contains the data to be retrieved, not a URI that points to the data to be retrieved)

func GetHTTPHeaders

func GetHTTPHeaders(ctx context.Context, url string) (http.Header, error)

GetHTTPHeaders returns the headers for the given URL

func GetMetadataFromURI

func GetMetadataFromURI(ctx context.Context, turi persist.TokenURI, ipfsClient *shell.Shell, arweaveClient *goar.Client) (persist.TokenMetadata, error)

GetMetadataFromURI parses and returns the NFT metadata for a given token URI

func GetOwnerOfERC721Token

func GetOwnerOfERC721Token(ctx context.Context, pContractAddress persist.EthereumAddress, pTokenID persist.HexTokenID, ethClient *ethclient.Client) (persist.EthereumAddress, error)

GetOwnerOfERC721Token returns the Owner of an ERC721 token

func GetTokenURI

func GetTokenURI(ctx context.Context, pTokenType persist.TokenType, pContractAddress persist.EthereumAddress, pTokenID persist.HexTokenID, ethClient *ethclient.Client) (persist.TokenURI, error)

GetTokenURI returns metadata URI for a given token address.

func NewEthClient

func NewEthClient() *ethclient.Client

NewEthClient returns an ethclient.Client

func NewStorageClient

func NewStorageClient(ctx context.Context) *storage.Client

func RetryGetTokenURI

func RetryGetTokenURI(ctx context.Context, tokenType persist.TokenType, contractAddress persist.EthereumAddress, tokenID persist.HexTokenID, ethClient *ethclient.Client) (persist.TokenURI, error)

RetryGetTokenURI calls GetTokenURI with backoff.

func RewriteURIToHTTP

func RewriteURIToHTTP(u string, isFxhash bool) string
