Types

type RelayError

type RelayError struct {
	Code    string        `json:"code"`
	Message string        `json:"message"`
	Retry   bool          `json:"retry,omitempty"`
	Delay   time.Duration `json:"delay,omitempty"`
}

RelayError represents a relay-specific error

func HandleError

func HandleError(err error) (*RelayError, error)

HandleError handles relay-specific errors and returns appropriate actions

func NewRelayError

func NewRelayError(code, message string) *RelayError

NewRelayError creates a new relay error

func (*RelayError) Error

func (e *RelayError) Error() string

Error implements the error interface

func (*RelayError) GetDelay

func (e *RelayError) GetDelay() time.Duration

GetDelay returns the delay before retry

func (*RelayError) IsRetryable

func (e *RelayError) IsRetryable() bool

IsRetryable returns true if the error can be retried

type RetryStrategy

type RetryStrategy struct {
	MaxRetries        int
	BackoffMultiplier float64
	MaxBackoff        time.Duration
	CurrentRetry      int
}

RetryStrategy defines retry behavior

func NewRetryStrategy

func NewRetryStrategy(maxRetries int, backoffMultiplier float64, maxBackoff time.Duration) *RetryStrategy

NewRetryStrategy creates a new retry strategy

func (*RetryStrategy) GetNextDelay

func (rs *RetryStrategy) GetNextDelay(err error) time.Duration

GetNextDelay calculates the delay for the next retry

func (*RetryStrategy) Reset

func (rs *RetryStrategy) Reset()

Reset resets the retry counter

func (*RetryStrategy) ShouldRetry

func (rs *RetryStrategy) ShouldRetry(err error) bool

ShouldRetry determines if an operation should be retried
