Functions ¶
func FormatTimePtr ¶
FormatTimePtr formats a time.Time pointer as an RFC3339 string pointer. Returns nil if the input is nil.
func Int64PtrToUint64 ¶
Int64PtrToUint64 safely converts *int64 to uint64 for API calls. Returns 0 if the pointer is nil. This is commonly used when converting domain model IDs to API parameter types.
WARNING: Negative values will wrap around to large uint64 values. This function assumes the input represents a valid ID (non-negative). If you need validation, check for negative values before calling this function.
func Int64PtrToUint64Ptr ¶
Int64PtrToUint64Ptr safely converts *int64 to *uint64. Returns nil if the pointer is nil. This is used when optional pointer types need to be converted.
WARNING: Negative values will wrap around to large uint64 values. This function assumes the input represents a valid ID (non-negative). If you need validation, check for negative values before calling this function.
func NowRFC3339Ptr ¶
func NowRFC3339Ptr() *string
NowRFC3339Ptr returns the current time as an RFC3339 formatted string pointer.
func ParseTimestampPtr ¶
ParseTimestampPtr safely parses a timestamp pointer into a time.Time pointer. Returns nil if the input is nil or empty, or a pointer to the parsed time. Returns an error if parsing fails.
func RetryWithExponentialBackoff ¶
func RetryWithExponentialBackoff(ctx context.Context, config RetryConfig, fn func() error) error
RetryWithExponentialBackoff executes a function with exponential backoff retry logic The delay between retries follows the formula: baseDelay * 2^(attempt-1) The delay is capped at maxDelay to prevent excessively long waits
func ValidateRFC3339 ¶
ValidateRFC3339 validates that a timestamp string is in RFC3339 format. Returns the parsed time.Time and nil error if valid, or zero time and error if invalid.
func ValidateRFC3339Ptr ¶
ValidateRFC3339Ptr validates a timestamp pointer string is in RFC3339 format. Returns nil error if the pointer is nil or contains a valid timestamp.
Types ¶
type RetryConfig ¶
RetryConfig holds retry configuration for operations
func NewRetryConfig ¶
func NewRetryConfig(maxAttempts int, baseDelay, maxDelay time.Duration) RetryConfig
NewRetryConfig creates a RetryConfig with specified parameters
