Types

type Pipeline

type Pipeline func(...interface{}) error

Pipeline is the func type for the pipeline result.

func Pipe

func Pipe(fs ...interface{}) Pipeline

Pipe accepts zero or more funcs fs and creates a pipeline.

A pipeline syncs outputs and inputs of consequent funcs together, such that the output of i'th func is the input of (i+1)'th func. Each func can accept zero or one input argument and return zero or one value with an optional error.

The last func is called a sink which only accepts an input argument and returns no value except an optional error; unless its return value will be ignored.

If a func in the pipeline fails with an error during the invocation, the pipe is broken immediately and the invocation returns an error.
