Struct ReconnectState 

pub struct ReconnectState { /* private fields */ }

Reconnection state tracker for managing connection attempts and backoff.

This helper tracks the number of reconnection attempts and calculates the appropriate backoff delay using exponential backoff.

Example

use monocoque_core::reconnect::ReconnectState;
use monocoque_core::options::SocketOptions;
use std::time::Duration;

let options = SocketOptions::default()
    .with_reconnect_ivl(Duration::from_millis(100))
    .with_reconnect_ivl_max(Duration::from_secs(10));

let mut reconnect = ReconnectState::new(&options);

// First attempt uses base interval
assert_eq!(reconnect.next_delay(), Duration::from_millis(100));

// Subsequent attempts use exponential backoff
assert_eq!(reconnect.next_delay(), Duration::from_millis(200));
assert_eq!(reconnect.next_delay(), Duration::from_millis(400));

// Reset on successful connection
reconnect.reset();
assert_eq!(reconnect.next_delay(), Duration::from_millis(100));

Implementations

impl ReconnectState

pub const fn new(options: &SocketOptions) -> ReconnectState

Create a new reconnection state tracker from socket options.

pub fn next_delay(&mut self) -> Duration

Get the delay for the next reconnection attempt.

This calculates the exponential backoff delay based on the number of previous attempts. The delay doubles with each attempt until it reaches reconnect_ivl_max.

Returns

The duration to wait before the next reconnection attempt.

pub fn reset(&mut self)

Reset the reconnection state after a successful connection.

This resets the attempt counter and interval back to the base values.

pub const fn attempt(&self) -> u32

Get the current attempt number.

pub const fn base_interval(&self) -> Duration

Get the base reconnection interval.

pub const fn max_interval(&self) -> Duration

Get the maximum reconnection interval.

pub const fn current_interval(&self) -> Duration

Get the current reconnection interval.
