# prefixsuffix

[![GoDoc](https://godoc.org/github.com/golang/gddo?status.svg)](https://godoc.org/github.com/ammario/prefixsuffix)

Exported [os/exec.prefixSuffixSaver](https://golang.org/src/os/exec/exec.go?s=19091:19652#L649).

```go

// Saver is an io.Writer which retains the first N bytes

// and the last N bytes written to it. The Bytes() methods reconstructs

// it with a pretty error message.

type Saver struct {

    N         int // max size of prefix or suffix

    // ...

}

```

## Basic Usage

```go

func something() {

    s := &prefixsuffix.Saver{N: 4}

    io.WriteString(s, "1234 --- 5678")

    fmt.Printf("%s\n", s.Bytes())   

    // 1234

    // ... omitting 5 bytes ...

    // 5678

}

```
