// Package xerrors implements functions to manipulate errors.
|
||
|
|
//
|
||
|
|
// This package is based on the Go 2 proposal for error values:
|
||
|
|
// https://golang.org/design/29934-error-values
|
||
|
|
//
|
||
|
|
// These functions were incorporated into the standard library's errors package
|
||
|
|
// in Go 1.13:
|
||
|
|
// - Is
|
||
|
|
// - As
|
||
|
|
// - Unwrap
|
||
|
|
//
|
||
|
|
// Also, Errorf's %w verb was incorporated into fmt.Errorf.
|
||
|
|
//
|
||
|
|
// Use this package to get equivalent behavior in all supported Go versions.
|
||
|
|
//
|
||
|
|
// No other features of this package were included in Go 1.13, and at present
|
||
|
|
// there are no plans to include any of them.
