Types

type Error

type Error struct {
	Description string
	Err         error
}

Error identifies an error. It has full support for errors.Is and errors.As, so the caller can ascertain the specific reason for the error by checking the underlying error.

func DBError

func DBError(kind ErrorKind, desc string) Error

DBError creates an Error given a set of arguments. This should only be used when creating errors related to the database.

func MsgError

func MsgError(kind ErrorKind, desc string) Error

MsgError creates an Error given a set of arguments. This should only be used when creating errors related to sending, receiving and processing messages.

func PoolError

func PoolError(kind ErrorKind, desc string) Error

PoolError creates an Error given a set of arguments. This should only be used when creating error related to the mining pool and its processes.

func (Error) Error

func (e Error) Error() string

Error satisfies the error interface and prints human-readable errors.

func (Error) Unwrap

func (e Error) Unwrap() error

Unwrap returns the underlying wrapped error.

type ErrorKind

type ErrorKind string

ErrorKind identifies a kind of error. It has full support for errors.Is and errors.As, so the caller can directly check against an error kind when determining the reason for an error.

func (ErrorKind) Error

func (e ErrorKind) Error() string

Error satisfies the error interface and prints human-readable errors.
