func (*Group) Shutdown ¶

func (g *Group) Shutdown() error

Shutdown runs shutdown handlers provided by each runner during registration, and exits if the shutdown timeout reached or all of the shutdown handler return. It returns non-nil error if one of the shutdown handlers returns error, or if the timeout is reached. The returned error type is ErrGroup (if it is non-nil).

func (*Group) Wait ¶

func (g *Group) Wait(ctx context.Context) *Group

Wait starts runners and returns if

1. The process receives SIGTERM or SIGINT.
2. One of the runner returns with non-nil error.
3. The input context is done.

When this function returns, the process no longer masks signal handling.
