You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: config.go
    path of file: ./repos/benthos/internal/component/buffer
    
    the code of the file until where you have to start completion: package buffer

import (
	"fmt"

	yaml "gopkg.in/yaml.v3"

	"github.com/benthosdev/benthos/v4/internal/docs"
)

// Config is the all encompassing configuration struct for all buffer types.
// Deprecated: Do not add new components here. Instead, use the public plugin
// APIs. Examples can be found in: ./internal/impl.
type Config struct {
	Type   string `json:"type" yaml:"type"`
	Plugin any    `json:"plugin,omitempty" y
    
func fromYAML(prov docs.Provider, value *yaml.Node) (conf Config, err error) {
	if conf.Type, _, err = docs.GetInferenceCandidateFromYAML(prov, docs.TypeBuffer, value); err != nil {
		err = docs.NewLintError(value.Line, docs.LintComponentNotFound, err)
		return
	}

	pluginNode, err := docs.GetPluginConfigYAML(conf.Type, value)
	if err != nil {
		err = docs.NewLintError(value.Line, docs.LintFailedRead, err)
		return
	}

	conf.Plugin = &pluginNode
	return
}
