Struct SupervisorTerm 

pub struct SupervisorTerm(/* private fields */);

The Cluster Supervisor term an ownership lease is granted under.

A lease is authority “issued under the current Cluster Supervisor term”: when a new Supervisor leader is elected the term advances, and a lease stamped with an older term no longer matches — its holder self-fences (FenceReason::TermSuperseded). This is the control-plane analogue of the replication term that fences a deposed primary (ADR 0030).

Implementations

impl SupervisorTerm

pub fn genesis() -> SupervisorTerm

The term a freshly-bootstrapped Supervisor starts at.

pub fn new(value: u64) -> SupervisorTerm

pub fn value(self) -> u64

pub fn next(self) -> SupervisorTerm

The next term, as minted when a new Supervisor leader is elected.

Trait Implementations

impl Clone for SupervisorTerm

fn clone(&self) -> SupervisorTerm

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SupervisorTerm

impl Debug for SupervisorTerm

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

Formats the value using the given formatter.

Formats the value using the given formatter.

impl Eq for SupervisorTerm

impl Ord for SupervisorTerm

fn cmp(&self, other: &SupervisorTerm) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for SupervisorTerm

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for SupervisorTerm

fn partial_cmp(&self, other: &SupervisorTerm) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
