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