Struct ClusterMember 

Source 
pub struct ClusterMember { /* private fields */ }
Expand description

One authorized cluster member.

The NodeIdentity is the member’s stable cluster identity — the same validated X.509 subject it authenticates and votes under. owned_range_count is the per-range role count, kept deliberately separate: a member’s cluster identity does not change when ranges move on or off it, and a freshly joined data member starts at zero.

Implementations§

Source§

impl ClusterMember

Source

pub fn joined_empty(identity: NodeIdentity, kind: MemberKind) -> ClusterMember

A member as it exists immediately after a successful join: authorized, of the granted kind, and holding no user ranges. Ranges are only assigned later by rebalancing or ownership transitions.

Source

pub fn identity(&self) -> &NodeIdentity

Source

pub fn kind(&self) -> MemberKind

Source

pub fn owned_range_count(&self) -> usize

How many user ranges this member currently owns. Distinct from cluster membership: a member with zero ranges is still a full member.

Source

pub fn holds_user_ranges(&self) -> bool

Does this member currently hold any user ranges? A just-joined member answers false until the rebalancer assigns ownership.

Source

pub fn assign_ranges(&mut self, count: usize)

Record that the rebalancer/ownership transitions have assigned this many user ranges to the member. This is the only path that gives a member ranges — join never does.
