# bufpipe: Buffered Pipe
|
|
|
|
[](https://circleci.com/gh/acomagu/bufpipe) [](https://godoc.org/github.com/acomagu/bufpipe)
|
|
|
|
The buffered version of io.Pipe. It's safe for concurrent use.
|
|
|
|
## How does it differ from io.Pipe?
|
|
|
|
Writes never block because the pipe has variable-sized buffer.
|
|
|
|
```Go
|
|
r, w := bufpipe.New(nil)
|
|
io.WriteString(w, "abc") // No blocking.
|
|
io.WriteString(w, "def") // No blocking, too.
|
|
w.Close()
|
|
io.Copy(os.Stdout, r)
|
|
// Output: abcdef
|
|
```
|

## How does it differ from bytes.Buffer?
|
|
|
|
Reads block if the internal buffer is empty until the writer is closed.
|
|
|
|
```Go
|
|
r, w := bufpipe.New(nil)
|
|
|
|
done := make(chan struct{})
|
|
go func() {
|
|
io.Copy(os.Stdout, r) // The reads block until the writer is closed.
|
|
done <- struct{}{}
|
|
}()
|
|
|
|
io.WriteString(w, "abc")
|
|
io.WriteString(w, "def")
|
|
w.Close()
|
|
<-done
|
|
// Output: abcdef
|
|
```
