golang-github-hashicorp-errwrap-dev binary package in Ubuntu Bionic amd64

 errwrap is a package for Go that formalizes the pattern of wrapping errors and
 checking if an error contains another error.
 .
 There is a common pattern in Go of taking a returned error value and then
 wrapping it (such as with fmt.Errorf) before returning it. The problem with
 this pattern is that you completely lose the original error structure.
 .
 Arguably the correct approach is that you should make a custom structure
 implementing the error interface, and have the original error as a field on
 that structure, such as this example. This is a good approach, but you have to
 know the entire chain of possible rewrapping that happens, when you might just
 care about one.
 .
 errwrap formalizes this pattern (it doesn't matter what approach you use above)
 by giving a single interface for wrapping errors, checking if a specific error
 is wrapped, and extracting that error.
 .
 This package contains the source.
