Functions

func As 

func As(err error, target any) bool

As is the equivalent of the std errors.As, and allows devs to only import this package for the capability.

func E added in v0.1.3 

func E(ctx context.Context, opt ...Option) error

E creates a new Err with provided code and supports the options of:

* WithoutEvent - allows you to specify that an error event should not be emitted.

* WithOp() - allows you to specify an optional Op (operation).

* WithMsg() - allows you to specify an optional error msg, if the default msg for the error Code is not sufficient.

* WithWrap() - allows you to specify an error to wrap. If the wrapped error is a boundary domain error, the wrapped error code will be used as the returned error's code.

* WithCode() - allows you to specify an optional Code, this code will be prioritized over a code used from WithWrap().

func EDeprecated added in v0.5.0 

func EDeprecated(opt ...Option) error

EDeprecated is the legacy version of E which does not create an event. Please refrain from using this. When all calls are moved from EDeprecated to E, please update ICU-1883

func Is 

func Is(err, target error) bool

Is the equivalent of the std errors.Is, but allows Devs to only import this package for the capability.

func IsCheckConstraintError 

func IsCheckConstraintError(err error) bool

IsCheckConstraintError returns a boolean indicating whether the error is known to report a check constraint violation.

func IsConflictError added in v0.12.0 

func IsConflictError(err error) bool

IsConflictError returns a boolean indicating whether the error is known to report a pre-conditional check violation or an aborted transaction.

func IsMissingTableError 

func IsMissingTableError(err error) bool

IsMissingTableError returns a boolean indicating whether the error is known to report a undefined/missing table violation.

func IsNotFoundError added in v0.1.3 

func IsNotFoundError(err error) bool

IsNotFoundError returns a boolean indicating whether the error is known to report a not found violation.

func IsNotNullError 

func IsNotNullError(err error) bool

IsNotNullError returns a boolean indicating whether the error is known to report a not-null constraint violation.

func IsUniqueError 

func IsUniqueError(err error) bool

IsUniqueError returns a boolean indicating whether the error is known to report a unique constraint violation.

func Match 

func Match(t *Template, err error) bool

Match the template against the error. The error must be of type *Err, or wrap an error of type *Err, otherwise match will return false. Matches all non-empty fields of the template against the error.

func New 

func New(ctx context.Context, c Code, op Op, msg string, opt ...Option) error

New creates a new Err with provided code, op and msg It supports the options of:

* WithWrap() - allows you to specify an error to wrap

func ToPbErrors added in v0.7.0 

func ToPbErrors(err *Err) *pberrors.Err

ToPbErrors will convert to an Err protobuf

func Wrap added in v0.1.3 

func Wrap(ctx context.Context, e error, op Op, opt ...Option) error

Wrap creates a new Err from the provided err and op, preserving the code from the originating error. It supports the options of:

* WithMsg() - allows you to specify an optional error msg, if the default msg for the error Code is not sufficient.

func WrapDeprecated added in v0.5.0 

func WrapDeprecated(e error, op Op, opt ...Option) error

WrapDeprecated is the legacy version of New which does not create an event. Please refrain from using this. When all calls are moved from WrapDeprecated to New, please update ICU-1884

)

func (Code) Info 

func (c Code) Info() Info

Info will look up the Code's Info. If the Info is not found, it will return Info for an Unknown Code.

func (Code) String 

func (c Code) String() string

String will return the Code's Info.Message

type Err 

type Err struct {
	// Code is the error's code, which can be used to get the error's
	// errorCodeInfo, which contains the error's Kind and Message
	Code Code

	// Msg for the error
	Msg string

	// Op represents the operation raising/propagating an error and is optional.
	// Op should be formatted as "package.func" for functions, while methods should
	// include the receiver type in parentheses "package.(type).func"
	Op Op

	// Wrapped is the error which this Err wraps and will be nil if there's no
	// error to wrap.
	Wrapped error
}

Err provides the ability to specify a Msg, Op, Code and Wrapped error. We've chosen Err over Error for the identifier to support the easy embedding of Errs. Errs can be embedded without a conflict between the embedded Err and Err.Error().

func Convert 

func Convert(e error) *Err

Convert will convert the error to a Boundary *Err (returning it as an error) and attempt to add a helpful error msg as well. If that's not possible, it will return nil

func FromPbErrors added in v0.7.0 

func FromPbErrors(pbErr *pberrors.Err) *Err

FromPbErrors will convert from Err protobuf

func (*Err) Error 

func (e *Err) Error() string

Error satisfies the error interface and returns a string representation of the Err

func (*Err) Info 

func (e *Err) Info() Info

Info about the Err

func (*Err) Unwrap 

func (e *Err) Unwrap() error

Unwrap implements the errors.Unwrap interface and allows callers to use the errors.Is() and errors.As() functions effectively for any wrapped errors.

type Info 

type Info struct {
	// Kind specifies the kind of error (unknown, parameter, integrity, etc).
	Kind Kind

	// Message provides a default message for the error code
	Message string
}

Info contains details of the specific error code

type Kind 

type Kind uint32

Kind specifies the kind of error (unknown, parameter, integrity, etc). 

const (
	Other Kind = iota
	Parameter
	Integrity
	Search
	Password
	Transaction
	Encryption
	Encoding
	State
	External
	VaultToken
)

func (Kind) String 

func (e Kind) String() string

type Op 

type Op string

Op represents an operation (package.function). For example iam.CreateRole

type Option 

type Option func(*Options)

Option - how Options are passed as arguments.

func WithCode added in v0.1.3 

func WithCode(code Code) Option

WithCode provides an option to provide a code when creating a new error.

func WithMsg 

func WithMsg(msg string, args ...any) Option

WithMsg provides an option to provide a message when creating a new error. If args are provided, the the msg string is used as a fmt specifier for the arguments and the resulting string is used as the msg.

func WithOp 

func WithOp(op Op) Option

WithOp provides an option to provide the operation that's raising/propagating the error.

func WithWrap 

func WithWrap(e error) Option

WithErrCode provides an option to provide an error to wrap when creating a new error.

func WithoutEvent added in v0.5.0 

func WithoutEvent() Option

WithoutEvent provides an option to suppress the event when wrapping or creating a new error.

type Options 

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

Options - how Options are represented.

func GetOpts 

func GetOpts(opt ...Option) Options

GetOpts - iterate the inbound Options and return a struct.

type Template 

type Template struct {
	Err       // Err embedded to support matching Errs
	Kind Kind // Kind allows explicit matching on a Template without a Code.
}

Template is useful constructing Match Err templates. Templates allow you to match Errs without specifying a Code. In other words, just Match using the Errs: Kind, Op, etc.

func T 

func T(args ...any) *Template

T creates a new Template for matching Errs. Invalid parameters are ignored. If more than is one parameter for a given type, only the last one is used.

func (*Template) Error 

func (t *Template) Error() string

Error satisfies the error interface but we intentionally don't return anything of value, in an effort to stop users from substituting Templates in place of Errs, when creating domain errors.

func (*Template) Info 

func (t *Template) Info() Info

Info about the Template, which is useful when matching a Template's Kind with an Err's Kind.
