func FromOperation(operation operationStatus) oeOpt

FromOperation is an option for construct operationStatus error from operationStatus FromOperation must use as `Operation(FromOperation(operationStatus))`

func HideEOF

func HideEOF(err error) error

func Is

func Is(err error, targets ...error) bool

Is is a improved proxy to errors.Is This need to single import errors

func IsOperationError

func IsOperationError(err error, codes ...Ydb.StatusIds_StatusCode) bool

IsOperationError reports whether err is operationError with given errType codes.

Transport returns a new transport error with given options

func WithAddress

func WithAddress(address string) teOpt

func WithIssues

func WithIssues(issues []*Ydb_Issue.IssueMessage) oeOpt

WithIssues is an option for construct operationStatus error with issues list WithIssues must use as `Operation(WithIssues(issues))`

func WithSkipDepth

func WithSkipDepth(skipDepth int) withStackTraceOption

func WithStackTrace

func WithStackTrace(err error, opts ...withStackTraceOption) error

WithStackTrace is a wrapper over original err with file:line identification
