func (*Announcer) Announce ¶
func (a *Announcer) Announce( ctx context.Context, memberIndex group.MemberIndex, sessionID string, ) ( []group.MemberIndex, error, )
Announce sends the member's readiness announcement for the given protocol session and listens for announcements from other group members. It returns a list of unique members indexes that are ready for the given attempt, including the executing member's index. The list is sorted in ascending order. This function blocks until the ctx passed as argument is done.
