Struct Slots 

pub struct Slots { /* private fields */ }

Two-slot compaction state for a single <kind>.<name> lifecycle.

Tracks the latest known-good create (confirmed) and the latest untested create (pending). See ADR 0005 for the state transition table this implements.

Implementations

impl Slots

pub fn new() -> Self

pub fn apply(&mut self, event: Event)

Apply one event to the state.

pub fn replay<I: IntoIterator<Item = Event>>(events: I) -> Self

Replay a sequence of events from an empty state.

pub fn threshold(&self) -> ThresholdPick

The dispatcher’s pick at threshold:

• pending set: try it; if it parse-fails, fall back to confirmed.
• no pending, confirmed set: start confirmed (no fallback).
• both empty: nothing to start.

pub fn confirmed(&self) -> Option<Scru128Id>

pub fn pending(&self) -> Option<Scru128Id>

Trait Implementations

impl Clone for Slots

fn clone(&self) -> Slots

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Slots

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

Formats the value using the given formatter.

impl Default for Slots

fn default() -> Slots

Returns the “default value” for a type.

impl Eq for Slots

impl PartialEq for Slots

fn eq(&self, other: &Slots) -> 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.
