# MustLog [](https://godoc.org/github.com/jmank88/mustlog) [](https://goreportcard.com/report/github.com/jmank88/mustlog)
An error-less go-kit/log extension.
## MustLogger
MustLogger extends log.Logger with Must, an error-less version of Log.
```go
mustLogger := NewMustLogger(&errLogger{}, func(err error, keyvals ...interface{}) {
fmt.Println("failed to log:", err)
})
mustLogger.Log("k", "v")
mustLogger.Log(poison, "poison")
mustLogger.Must("k", "v")
mustLogger.Must(poison, "poison")
```
Output:
```text
k v
k v
failed to log: poisoned
```
## MustContext
MustContext extends log.Context to implement MustLogger.
```go
mustContext := NewMustContext(&errLogger{}, func(err error, keyvals ...interface{}) {
fmt.Println("failed to log:", err)
})
mustContext.Must("k", "v")
mustContext.Must(poison, "poison")
mustContext = mustContext.With("withK", "withV")
mustContext.Must("k", "v")
mustContext.Must(poison, "poison")
mustContext = mustContext.WithPrefix("prefixK", "prefixV")
mustContext.Must("k", "v")
mustContext.Must(poison, "poison")
```
Output:
```text
k v
failed to log: poisoned
withK withV k v
failed to log: poisoned
prefixK prefixV withK withV k v
failed to log: poisoned
```
