Struct ExponentialBackoff 

pub struct ExponentialBackoff { /* private fields */ }

Exponential backoff calculator (trueno-viz pattern)

Calculates retry delays with exponential growth and optional jitter. Useful for retry logic in network operations.

Implementations

impl ExponentialBackoff

pub fn new(base_us: u64, max_us: u64) -> Self

Create a new exponential backoff

Arguments

• base_us - Base delay in microseconds
• max_us - Maximum delay in microseconds

pub fn with_jitter(self) -> Self

Create with jitter enabled

pub fn with_multiplier(self, multiplier: f64) -> Self

Create with custom multiplier

pub fn for_network() -> Self

Create for network retries (100ms base, 30s max, with jitter)

pub fn for_fast() -> Self

Create for fast retries (10ms base, 1s max)

pub fn next_delay(&mut self) -> u64

Get next delay and increment attempt (O(1))

pub fn current_delay(&self) -> u64

Get current delay without incrementing (O(1))

pub fn current_delay_ms(&self) -> u64

Get current delay in milliseconds

pub fn attempt(&self) -> u64

Get attempt count

pub fn is_at_max(&self) -> bool

Check if at max delay

pub fn reset(&mut self)

Reset to first attempt

Trait Implementations
