Expand description

A record stored in the DHT.

Fields

key: Key

Key of the record.

value: Vec<u8>

Value of the record.

publisher: Option<PeerId>

The (original) publisher of the record.

expires: Option<Instant>

The expiration time as measured by a local, monotonic clock.

Implementations

source

impl Record

source

pub fn new<K>(key: K, value: Vec<u8>) -> Self where
K: Into<Key>,

Creates a new record for insertion into the DHT.

source

pub fn is_expired(&self, now: Instant) -> bool

Checks whether the record is expired w.r.t. the given Instant.

Trait Implementations

source

impl Clone for Record

source

fn clone(&self) -> Record

Returns a copy of the value. Read more

1.0.0 · source

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

Performs copy-assignment from source. Read more

source

impl Debug for Record

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

Formats the value using the given formatter. Read more

source

impl PartialEq<Record> for Record

source

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

This method tests for self and other values to be equal, and is used by ==. Read more

1.0.0 · source

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason. Read more
