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: cache.go
    path of file: ./repos/podman/vendor/github.com/go-playground/validator/v10
    
    the code of the file until where you have to start completion: package validator

import (
	"fmt"
	"reflect"
	"strings"
	"sync"
	"sync/atomic"
)

type tagType uint8

const (
	typeDefault tagType = iota
	typeOmitEmpty
	typeIsDefault
	typeNoStructLevel
	type
    
func (sc *structCache) Set(key reflect.Type, value *cStruct) {
	m := sc.m.Load().(map[reflect.Type]*cStruct)
	nm := make(map[reflect.Type]*cStruct, len(m)+1)
	for k, v := range m {
		nm[k] = v
	}
	nm[key] = value
	sc.m.Store(nm)
}
