# go-temp-err-catcher
This is a little package to use with your net.Listeners.
Docs: https://godoc.org/github.com/jbenet/go-temp-err-catcher
Get:
go get github.com/jbenet/go-temp-err-catcher
## Examples
It is meant to be used with things like net.Lister.Accept:
```go
import (
tec "github.com/jbenet/go-temp-err-catcher"
)
func listen(listener net.Listener) {
var c tec.TempErrCatcher
for {
conn, err := listener.Accept()
if err != nil && c.IsTemporary(c) {
continue
}
return conn, err
}
}
```
You can make your errors implement `Temporary`:
```go
type errTemp struct {
e error
}
func (e errTemp) Temporary() bool {
return true
}
func (e errTemp) Error() string {
return e.e.Error()
}
err := errors.New("beep boop")
var c tec.TempErrCatcher
c.IsTemporary(err) // false
c.IsTemporary(errTemp{err}) // true
```
Or just use `ErrTemp`:
```go
err := errors.New("beep boop")
var c tec.TempErrCatcher
c.IsTemporary(err) // false
c.IsTemporary(tec.ErrTemp{err}) // true
```
You can also define an `IsTemp` function to classify errors:
```go
var ErrSkip = errors.New("this should be skipped")
var ErrNotSkip = errors.New("this should not be skipped")
var c tec.TempErrCatcher
c.IsTemp = func(e error) bool {
return e == ErrSkip
}
c.IsTemporary(ErrSkip) // true
c.IsTemporary(ErrNotSkip) // false
c.IsTemporary(ErrTemp) // false! no longer accepts Temporary()
```
