Functions

func ErrMaxConcurrentQueriesLimitExceeded

func ErrMaxConcurrentQueriesLimitExceeded(n, limit int) error

ErrMaxConcurrentQueriesLimitExceeded is an error when the query cannot be run because the maximum number of queries has been reached.

func IsTimeout

func IsTimeout(err error) bool

IsTimeout returns true if the error was caused by a timeout.

Types

type ErrQueryTimeout

type ErrQueryTimeout struct {
	// contains filtered or unexported fields
}

ErrQueryTimeout is returned when a query times out executing.

func NewErrQueryTimeout

func NewErrQueryTimeout(err error) *ErrQueryTimeout

NewErrQueryTimeout wraps the provided causing error as an ErrQueryTimeout.

func (*ErrQueryTimeout) Code

func (e *ErrQueryTimeout) Code() int

Code returns an HTTP 504.

func (*ErrQueryTimeout) Error

func (e *ErrQueryTimeout) Error() string

Error returns the error string of the causing error.

func (*ErrQueryTimeout) InnerError

func (e *ErrQueryTimeout) InnerError() error

InnerError returns the cause of the query timeout.
