The Big Picture

Sets governance participants.

Use Cases

Initialize Senate

From Chain Metadata

Set the collective's membership. `new_members`: The new member list. Be nice to the chain and provide it sorted. `prime`: The prime member whose vote sets the default. `old_count`: The upper bound for the previous number of members in storage. Used for weight estimation. The dispatch of this call must be `SetMembersOrigin`. NOTE: Does not enforce the expected `MaxMembers` limit on the amount of members, but the weight estimations rely on it to estimate dispatchable weight.

Input Parameters

#	Name	Type	Description
0	new_members	Vec<AccountId> Vec	new_members (Vec<AccountId>)
1	prime	Option	prime (Option)
2	old_count	u32	old_count (u32)
