# chann ![example workflow](https://github.com/golang-design/chann/actions/workflows/chann.yml/badge.svg) ![](https://changkun.de/urlstat?mode=github&repo=golang-design/chann)

a unified channel package in Go

```go

import "golang.design/x/chann"

```

This package requires Go 1.18.

## Basic Usage

Different types of channels:

```go

ch := chann.New[int]()                  // unbounded, capacity unlimited

ch := chann.New[func()](chann.Cap(0))   // unbufferd, capacity 0

ch := chann.New[string](chann.Cap(100)) // buffered,  capacity 100

```

Send and receive operations:

```go

ch.In() <- 42

println(<-ch.Out()) // 42

```

Close operation:

```go

ch.Close()

```

Channel properties:

```go

ch.Len() // the length of the channel

ch.Cap() // the capacity of the channel

```

See https://golang.design/research/ultimate-channel for more details of

the motivation of this abstraction.
