Struct ExpireStats 

pub struct ExpireStats {
    pub sampled: u32,
    pub expired: u32,
    pub rounds: u32,
}

What Store::tick_expire saw and did. Surfaced for tests, INFO keyspace, and (eventually) Wave 2 task #4’s crash-safe verifier.

Fields

sampled: u32

Total TTL-bearing keys sampled across all rounds.

expired: u32

How many of those were past their deadline and got removed.

rounds: u32

Rounds executed before the loop exited (either max_rounds reached or in-batch expire-rate dropped below the continuation threshold).

Trait Implementations

impl Clone for ExpireStats

fn clone(&self) -> ExpireStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ExpireStats

impl Debug for ExpireStats

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

Formats the value using the given formatter.

impl Default for ExpireStats

fn default() -> ExpireStats

Returns the “default value” for a type.

impl Eq for ExpireStats

impl PartialEq for ExpireStats

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