circbuf
|

|
|
=======
|
||
|
|
|
||
|
|
This repository provides the `circbuf` package. This provides a `Buffer` object
|
||
|
|
which is a circular (or ring) buffer. It has a fixed size, but can be written
|
||
|
|
to infinitely. Only the last `size` bytes are ever retained. The buffer implements
|
||
|
|
the `io.Writer` interface.

Usage
|
||
|
|
=====
|
||
|
|
|
||
|
|
The `circbuf` package is very easy to use:
|
||
|
|
|
||
|
|
```go
|
||
|
|
buf, _ := NewBuffer(6)
|
||
|
|
buf.Write([]byte("hello world"))
|
||
|
|
|
||
|
|
if string(buf.Bytes()) != " world" {
|
||
|
|
panic("should only have last 6 bytes!")
|
||
|
|
}
|
||
|
|
|
||
|
|
```
