fmt.Println(err)
})
panic("string error")
}

func StackTrace ¶
func StackTrace() string

Types ¶
type AggregatedError ¶ added in v0.3.0
type AggregatedError []error
AggregatedError is an array of errors. It implements error interface and aggregates multiple errors.
Example ¶
package main
import (
"errors"
"fmt"
"github.com/Prastiwar/Go-flow/exception"
)
func main() {
aggErr := exception.Aggregate(
errors.New("'' is not valid value for title"),
errors.New("title is required"),
)
err := fmt.Errorf("(%v) validation errors: %w", len(aggErr), aggErr)
fmt.Println(err)
}
Output: (2) validation errors: ["'' is not valid value for title", "title is required"]
func Aggregate ¶ added in v0.3.0
func Aggregate(errs ...error) AggregatedError
Aggregate returns AggregatedError filled with specified errors. This is helper function to use variadic errors as cast to AggregatedError.
func (AggregatedError) Error ¶ added in v0.3.0
func (err AggregatedError) Error() string
func (AggregatedError) Flat ¶ added in v0.3.0
func (err AggregatedError) Flat() AggregatedError
Flat returns AggregatedError with flat one-dimensional array. Any nested AggregatedError will be unwrapped.
