错误的类型接口实现

Question

我正在尝试按照Prisma 的指南来设置 GraphQL Go 服务器。解析器.gopackage mainimport (    "context"    "prismago/hello-world/generated/prisma-client")// Resolver structtype Resolver struct {    Prisma *prisma.Client}// Mutation MutationResolverfunc (r *Resolver) Mutation() MutationResolver {    return &mutationResolver{r}}// Post PostResolverfunc (r *Resolver) Post() PostResolver {    return &postResolver{r}}// Query QueryResolverfunc (r *Resolver) Query() QueryResolver {    return &queryResolver{r}}// User UserResolverfunc (r *Resolver) User() UserResolver {    return &userResolver{r}}type mutationResolver struct{ *Resolver }func (r *mutationResolver) CreateUser(ctx context.Context, name string) (*prisma.User, error) {    return r.Prisma.CreateUser(prisma.UserCreateInput{        Name: name,    }).Exec(ctx)}func (r *mutationResolver) CreateDraft(ctx context.Context, title string, userID string) (*prisma.Post, error) {    return r.Prisma.CreatePost(prisma.PostCreateInput{        Title: title,        Author: &prisma.UserCreateOneWithoutPostsInput{            Connect: &prisma.UserWhereUniqueInput{ID: &userID},        },    }).Exec(ctx)}func (r *mutationResolver) Publish(ctx context.Context, postID string) (*prisma.Post, error) {    published := true    return r.Prisma.UpdatePost(prisma.PostUpdateParams{        Where: prisma.PostWhereUniqueInput{ID: &postID},        Data:  prisma.PostUpdateInput{Published: &published},    }).Exec(ctx)}type postResolver struct{ *Resolver }func (r *postResolver) Author(ctx context.Context, obj *prisma.Post) (*prisma.User, error) {    return r.Prisma.Post(prisma.PostWhereUniqueInput{ID: &obj.ID}).Author().Exec(ctx)}type queryResolver struct{ *Resolver }func (r *queryResolver) PublishedPosts(ctx context.Context) ([]prisma.Post, error) {    published := true    return r.Prisma.Posts(&prisma.PostsParams{        Where: &prisma.PostWhereInput{Published: &published},    }).Exec(ctx)}

修改generated.go文件接口以接受返回的[]prisma.Post而不是[]*prisma.Post.

改变：

type UserResolver interface {
    Posts(ctx context.Context, obj *prisma.User) ([]*prisma.Post, error)
}

到：

type UserResolver interface {
    Posts(ctx context.Context, obj *prisma.User) ([]prisma.Post, error)
}
