Struct Retry 

pub struct Retry {
    pub max_attempts: u32,
    pub backoff: Backoff,
}

Retry configuration for SNMP requests.

Controls how the client handles timeouts on UDP transports. TCP transports ignore retry configuration since the transport layer handles reliability.

Examples

use async_snmp::Retry;
use std::time::Duration;

// No retries
let retry = Retry::none();

// Fixed delay between retries
let retry = Retry::fixed(3, Duration::from_millis(200));

// Exponential backoff with jitter (1s, 2s, 4s, 5s, 5s)
let retry = Retry::exponential(5)
    .max_delay(Duration::from_secs(5))
    .jitter(0.25)
    .build();

Fields

max_attempts: u32

Maximum number of retry attempts (0 = no retries, request sent once)

backoff: Backoff

Backoff strategy between retries

Implementations

impl Retry

pub fn none() -> Self

No retries - request is sent once and fails on timeout.

pub fn fixed(attempts: u32, delay: Duration) -> Self

Fixed delay between retries.

Arguments

• attempts - Maximum number of retry attempts
• delay - Fixed delay before each retry

pub fn exponential(attempts: u32) -> RetryBuilder

Start building an exponential backoff retry configuration.

Returns a RetryBuilder for configuring the backoff parameters.

Arguments

• attempts - Maximum number of retry attempts

Example

use async_snmp::Retry;
use std::time::Duration;

let retry = Retry::exponential(5)
    .max_delay(Duration::from_secs(5))
    .jitter(0.25)
    .build();

pub fn compute_delay(&self, attempt: u32) -> Duration

Compute the delay before the next retry attempt.

Returns Duration::ZERO for Backoff::None.
