	return _sliceEncoderPool.Get().(*sliceArrayEncoder)
}

func putSliceEncoder(e *sliceArrayEncoder) {
	e.elems = e.elems[:0]

// NewConsoleEncoder creates an encoder whose output is designed for human -
// rather than machine - consumption. It serializes the core log entry data
// (message, level, timestamp, etc.) in a plain-text format and leaves the
// structured context as JSON.
//
// Note that although the console encoder doesn't use the keys specified in the
// encoder configuration, it will omit any element whose key is set to the empty
// string.
func NewConsoleEncoder(cfg EncoderConfig) Encoder {

	line := bufferpool.Get()

	// We don't want the entry's metadata to be quoted and escaped (if it's
	// encoded as strings), which means that we can't use the JSON encoder. The
	// simplest option is to use the memory encoder and fmt.Fprint.
	//
	// If this ever becomes a performance bottleneck, we can implement
	// ArrayEncoder for our plain-text format.

Review comment (suggestion):
nit:

```suggestion
		// Default delimiter '\t'
```
