Types ¶
type PrefixSuffixSaver ¶
type PrefixSuffixSaver struct {
N int // max size of prefix or suffix
// contains filtered or unexported fields
}
PrefixSuffixSaver is an io.Writer which retains the first N bytes and the last N bytes written to it. The Bytes method reconstructs it with a pretty error message. It is copied from os/exec/exec.go of the Go stdlib.
func (*PrefixSuffixSaver) Bytes ¶
func (w *PrefixSuffixSaver) Bytes() []byte
Bytes returns a slice of the bytes, or a copy of the bytes, retained by w. If more bytes than could be retained were written to w, it returns a concatenation of the N first bytes, a message for how many bytes were dropped, and the N last bytes.
