Overview ▾

Package multi is an error type that holds multiple errors. These errors typically originate from operations that target multiple nodes. For example, a transaction proposal with two endorsers could return a multi error type if both endorsers return errors

▾ Example

Code:

errs := Errors{}
errs = append(errs, fmt.Errorf("peer0 failed"))
errs = append(errs, fmt.Errorf("peer1 failed"))

// Multi errors implement the standard error interface and are returned as regular errors
err := interface{}(errs).(error)

// We can extract multi errors from a standard error
errs, ok := err.(Errors)
fmt.Println(ok)

// And handle each error individually
for _, e := range errs {
    fmt.Println(e)
}

Output:

true
peer0 failed
peer1 failed

func Append 

func Append(errs error, err error) error

Append error to Errors. If the first arg is not an Errors object, one will be created

func New 

func New(errs ...error) error

New Errors object with the given errors. Only non-nil errors are added.

type Errors

Errors is used to represent multiple errors 

type Errors []error

func (Errors) Error 

func (errs Errors) Error() string

Error implements the error interface to return a string representation of Errors

func (Errors) ToError 

func (errs Errors) ToError() error

ToError converts Errors to the error interface returns nil if no errors are present, a single error object if only one is present
