Enum SovereignRole 

pub enum SovereignRole {
    Voter,
    NonVoter,
}

Whether a node in a sovereign group may hold a seat in that group’s quorum — R605-F12.

This is not a placement input and not a taint. It narrows a Membership, and the single thing that reads it is join_permitted.

Self::Voter is the default because it is what every already-stamped node means today: before this enum existed, declaring a group was declaring quorum eligibility, so absence has to keep meaning that or the field would silently retire six live voters. The permissiveness is bounded by the group still being mandatory — a box cannot drift into a quorum without an operator naming the group first — and the camp lints the omission at the layer that can see the whole fleet (cloud::validate::check_unroled_sovereign_members), rather than here, where refusing to deserialize would break every node that predates the field.

Variants

Voter

Quorum-eligible: may be joined into its group’s cluster.

NonVoter

In the group’s blast radius — shares its upgrade cadence, its secrets, its destruction — but never a quorum seat. Refused by join_permitted on either side of a join.

Implementations

impl SovereignRole

pub fn as_str(&self) -> &'static str

The wire/TOML spelling: "voter" / "non-voter". Matches the serde rename so the CLI flag, the TOML value and the /raft/status JSON can never disagree about how the value is written.

pub fn is_voter(&self) -> bool

True for Self::Voter. Named rather than matched at call sites so the join rule reads as one predicate.

Trait Implementations

impl Clone for SovereignRole

fn clone(&self) -> SovereignRole

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for SovereignRole

impl Debug for SovereignRole

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for SovereignRole

fn default() -> SovereignRole

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SovereignRole

fn deserialize<__D>( __deserializer: __D, ) -> Result<SovereignRole, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for SovereignRole

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Eq for SovereignRole

impl FromStr for SovereignRole

fn from_str(s: &str) -> Result<SovereignRole, <SovereignRole as FromStr>::Err>

Parses the two legal spellings and nothing else. The error names both, because this is reached from a CLI flag where the operator has a typo in hand and no schema to consult.

type Err = String

The associated error which can be returned from parsing.

impl PartialEq for SovereignRole

fn eq(&self, other: &SovereignRole) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for SovereignRole

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
