Constants

const InvalidErrorType = Const("Invalid type for error")

InvalidErrorType is the error returned by From when the type is not an error.

Functions

func From

func From(value interface{}) error

From converts from any value to an error safely. If the value is a nil, an untyped nil is returned. If the value is not nil, but does not implement error, InvalidErrorType is returned.

Types

type Const

type Const string

Const is the type for constant error values.

func (Const) Error

func (e Const) Error() string

Error implements error for Const returning the string value of the const.

type List

type List []error

List is the type for a list of errors.

func (*List) Collect

func (l *List) Collect(err error)

Collect adds an error to the list.

func (*List) First

func (l *List) First() error

First returns the first error added to it.

type One

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

One is the type for something that collects only the first error.

func (*One) Collect

func (o *One) Collect(err error)

Collect adds an error to the list.

func (*One) First

func (o *One) First() error

First returns the first error added to it.
