func New(ctx context.Context, cfg *config.Config) (*sqlx.DB, func(), error)

MySQLへのコネクションを確立して返す

Types ¶

type Beginner ¶

type Beginner interface {
	BeginTx(ctx context.Context, opts *sql.TxOptions) (*sql.Tx, error)
}

type Execer ¶

type Execer interface {
	ExecContext(ctx context.Context, query string, args ...any) (sql.Result, error)
	NamedExecContext(ctx context.Context, query string, arg interface{}) (sql.Result, error)
}

書き込み系の操作

type Preparer ¶

type Preparer interface {
	PreparexContext(ctx context.Context, query string) (*sqlx.Stmt, error)
}

type Queryer ¶

type Queryer interface {
	Preparer
	QueryxContext(ctx context.Context, query string, args ...any) (*sqlx.Rows, error)
	QueryRowxContext(ctx context.Context, query string, args ...any) *sqlx.Row
	GetContext(ctx context.Context, dest interface{}, query string, args ...any) error
	SelectContext(ctx context.Context, dest interface{}, query string, args ...any) error
}

参照系の操作

type Repository ¶

type Repository struct {
	Clocker clock.Clocker
}

RDBMSに対する永続化操作を一つのRepository構造体のメソッドとして実装するメリット 1. 複数のテーブルを一つの型のメソッドで操作できる 2. DIを利用する場合、一つの型にまとまっていたほうが取り回しがしやすい

) error

func (*Repository) ListTasks ¶

func (r *Repository) ListTasks(

) (entity.Tasks, error)

func (*Repository) RegisterUser ¶

func (r *Repository) RegisterUser(ctx context.Context, db Execer, u *entity.User) error

type TaskStore ¶

type TaskStore struct {
	LastID entity.TaskID
	Tasks  map[entity.TaskID]*entity.Task
}

func (*TaskStore) Add ¶
