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: provider.go
    path of file: ./repos/moby/vendor/github.com/Microsoft/go-winio/pkg/etw
    
    the code of the file until where you have to start completion: //go:build windows
// +build windows

package etw

import (
	"crypto/sha1" //nolint:gosec // not used for secure application
	"encoding/binary"
	"strings"
	"unicode/utf16"

	"github.com/Microsoft/go-winio/pkg/guid"
	"golang.org/x/sys/windows"
)

// Provider represents an ETW event provider. It is identified by 
    
func (provider *Provider) IsEnabledForLevelAndKeywords(level Level, keywords uint64) bool {
	if provider == nil {
		return false
	}

	if !provider.enabled {
		return false
	}

	// ETW automatically sets the level to 255 if it is specified as 0, so we
	// don't need to worry about the level=0 (all events) case.
	if level > provider.level {
		return false
	}

	if keywords != 0 && (keywords&provider.keywordAny == 0 || keywords&provider.keywordAll != provider.keywordAll) {
		return false
	}

	return true
}
