Functions

func IsBalanceError

func IsBalanceError(err error) bool

IsBalanceError returns true if err is either InsufficientFundsError or EmptyWalletError.

Types

type EmptyWalletError

type EmptyWalletError struct {
	Code          string `json:"code"`
	WalletAddress string `json:"walletAddress"`
}

EmptyWalletError indicates the wallet has a zero balance.

func IsEmptyWalletError

func IsEmptyWalletError(err error) (*EmptyWalletError, bool)

IsEmptyWalletError reports whether err is an EmptyWalletError.

func NewEmptyWalletError

func NewEmptyWalletError(wallet string) *EmptyWalletError

NewEmptyWalletError creates an EmptyWalletError.

func (*EmptyWalletError) Error

func (e *EmptyWalletError) Error() string

type InsufficientFundsError

type InsufficientFundsError struct {
	Code              string  `json:"code"`
	CurrentBalanceUSD float64 `json:"currentBalanceUSD"`
	RequiredUSD       float64 `json:"requiredUSD"`
	WalletAddress     string  `json:"walletAddress"`
}

InsufficientFundsError indicates the wallet balance is too low for the requested operation.

func IsInsufficientFundsError

func IsInsufficientFundsError(err error) (*InsufficientFundsError, bool)

IsInsufficientFundsError reports whether err is an InsufficientFundsError.

func NewInsufficientFundsError

func NewInsufficientFundsError(wallet string, current, required float64) *InsufficientFundsError

NewInsufficientFundsError creates an InsufficientFundsError.

func (*InsufficientFundsError) Error

func (e *InsufficientFundsError) Error() string

type RpcError

type RpcError struct {
	Code          string `json:"code"`
	OriginalError error  `json:"-"`
}

RpcError wraps a low-level RPC failure.

func IsRpcError

func IsRpcError(err error) (*RpcError, bool)

IsRpcError reports whether err is an RpcError.

func NewRpcError

func NewRpcError(original error) *RpcError

NewRpcError creates an RpcError wrapping the original error.

func (*RpcError) Error

func (e *RpcError) Error() string

func (*RpcError) Unwrap

func (e *RpcError) Unwrap() error
