Struct stronghold_rlu::breaker::BusyBreaker

pub struct BusyBreaker { /* private fields */ }

BusyBreaker

BusyBreaker is kind of a circuit-breaker and busy keeper for short delays on spin loops on the CPU.

Example

Implementations

impl BusyBreaker

pub fn new(max_trips: usize) -> Self

Creates a new BusyBreaker with a configurable number of exponential trips before the breaker trips. In the latter case an error is being returned.

pub fn spin(&self) -> Result<(), BusyBreakerError>

Keeps the CPU busy but hints to the CPU reschedule the CPU time

core::hint::spin_loop() may be available on the integrating system, otherwise this function call is just a busy loop, that wastes some CPU cycles

pub fn reset(&self)

Resets the breaker to zero
