Struct SettledDeletionRule 

pub struct SettledDeletionRule {
    pub leader: bool,
    pub approvals: u16,
    pub approvers_predate_document: bool,
}

Who must approve a moderator’s deletion of a settled document: one past the window its document type gives its moderators (moderatorAbilities.deleteWithin). The document type’s moderatorAbilities.deleteSettled (protocol version 14), on a contract whose moderators are an elected team: so many members of the seated team, the leader counted among them when it approves, and the leader among them only when leader is set; with leader unset, any members meet it. While approvers_predate_document is set, a member the leader added counts only for documents created after its addition.

Fields

leader: bool

Whether the team’s leader must be among the approvals.

approvals: u16

How many moderators of the seated team must approve, the leader counted among them: at least 1, and at registration at most the members the declared team can hold (its leader, SystemLimits::max_moderation_charter_elected_members elected members and the declaration’s maxAddedModerators). A seated team that can hold fewer, its charter electing fewer members, must have all it can hold approve.

approvers_predate_document: bool

Whether a member the leader added (an addedModerator) proposes or approves the deletion of a document only when its addition was made before the document was created (approversPredateDocument, default true when approvals is above 1: a rule one approval meets, the leader meets alone). The leader names whom it adds, so without this it could add members who approve whatever it proposes, and take them off again once they had. The leader and the elected members always count: the election seated them, not the leader. Read from the document’s $createdAt, which the type must then require at registration; a document without it admits no added member. What the rule needs is not lowered for it (see Self::approvals_needed), so a team whose members from before a document are too few never deletes that document once settled. Every addition comes after the seat, so a document written before the seat counts only the leader and the elected members: under a rule asking for more approvals than those, the team never deletes any document older than the seat once settled.

Implementations

impl SettledDeletionRule

pub fn approvals_needed(&self, team_capacity: usize) -> usize

How many approvals meet the rule on a team that holds at most team_capacity members, the leader counted: its approvals, or all the team can hold when it asks for more, so that it can be met by the team seated.

pub fn is_met_by( &self, approvals: &[Identifier], leader_id: Identifier, team_capacity: usize, ) -> bool

Whether approvals, identities of the seated team led by leader_id, each at most once, meet the rule on a team that holds at most team_capacity members (Self::approvals_needed), the leader among them when the rule says so.

pub fn admits_addition( &self, added_at: TimestampMillis, document_created_at: TimestampMillis, ) -> bool

Whether a member the leader added at added_at (its addedModerator’s $createdAt) may approve the deletion of a document created at document_created_at: always when approvers_predate_document is unset, and otherwise only when added before it. An addition in the same block as the document, at the same time, does not count: which of the two came first is not something the leader should be able to choose.
