Struct hyparview::TimeToLive

pub struct TimeToLive(_);

TTL of a message.

It decreases by one each time the message is forwarded. If the TTL of a message reaches zero, the message will be handled by the node that keeps the message at the time. So, a TTL can be regarded as the hop count of a message.

Methods

impl TimeToLive

pub fn new(ttl: u8) -> Self

Makes a new TimeToLive instance.

pub fn as_u8(self) -> u8

Returns the value of the TTL.

pub fn is_expired(self) -> bool

Returns true if the TTL is expired, otherwise false.

Examples

use hyparview::TimeToLive;

let ttl = TimeToLive::new(10);
assert!(!ttl.is_expired());

let ttl = TimeToLive::new(0);
assert!(ttl.is_expired());
