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: bigcache.go
    path of file: ./repos/gocache/store/bigcache
    
    the code of the file until where you have to start completion: package bigcache

import (
	"context"
	"errors"
	"fmt"
	"strings"
	"time"

	"github.com/eko/gocache/lib/v4/store"
)

// BigcacheClientInterface represents a allegro/bigcache client
type BigcacheClientInterface interface {
	Get(key string) ([]byte, error)
	Set
    
func (s *BigcacheStore) Get(_ context.Context, key any) (any, error) {
	item, err := s.client.Get(key.(string))
	if err != nil {
		return nil, err
	}
	if item == nil {
		return nil, store.NotFoundWithCause(errors.New("unable to retrieve data from bigcache"))
	}

	return item, err
}
