Struct NetworkRetry 

pub struct NetworkRetry {
    pub reconnect_interval: u16,
    pub maximum_retries: u32,
    /* private fields */
}

Available on crate feature network-client and non-WebAssembly only.

Network retry state and logic for exponential backoff.

Fields

reconnect_interval: u16

Reconnect interval.

maximum_retries: u32

Maximum number of retries.

Implementations

impl NetworkRetry

pub fn new(maximum_retries: u32, reconnect_interval: u16) -> Self

Create a new network retry.

The reconnect interval is a base interval in milliseconds for the exponential backoff so use a small value such as 1000 or 2000.

pub fn delay(&self, retries: u32) -> Result<u64, Error>

Exponential backoff millisecond delay for a retry counter.

pub fn retries(&self) -> u32

Current number of retries.

pub fn maximum(&self) -> u32

Maximum number of retries.

pub fn reset(&self)

Reset retries counter.

pub fn clone_reset(&self) -> Self

Clone of this network retry with the retry counter reset.

pub fn increment(&self) -> u32

Increment for next retry attempt.

pub fn is_exhausted(&self, retries: u32) -> bool

Determine if retry attempts are exhausted.

pub async fn wait_and_retry<D, T, F>( &self, id: D, retries: u32, callback: F, cancel: Receiver<CancelReason>, ) -> Result<T, Error>

where D: Display, F: Future<Output = T>,

Wait and then retry.

Trait Implementations

impl Debug for NetworkRetry

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