func RecoverInto

func RecoverInto(errp *error)

RecoverInto is a function you can defer-call at the start of a function that you know has a risk of panicking.

Example

package main

import (
	"fmt"

	"github.com/itchio/butler/butlerd/horror"
)

func main() {
	f := func() (retErr error) {
		defer horror.RecoverInto(&retErr)
		panic("Oh no")
	}
	err := f()
	fmt.Printf("Returned from f: %+v", err)
}
