shadow_rs::host::cpu

Struct Cpu

pub struct Cpu { /* private fields */ }

Expand description

Accounts for time executing code on the native CPU, calculating a corresponding delay for when the simulated CPU should be allowed to run next.

Implementations§

impl Cpu

pub fn new( simulated_frequency: u64, native_frequency: u64, threshold: Option<SimulationTime>, precision: Option<SimulationTime>, ) -> Self

threshold: if None, never report a delay. Otherwise only report a delay after it is more than this threshold.

precision: if provided, round individual native delays to this granularity (rounding up at midpoint). Panics if this is Some(0).

pub fn update_time(&mut self, now: EmulatedTime)

Configure the current time.

pub fn add_delay(&mut self, native_delay: Duration)

Account for native_delay spent natively executing code.

pub fn delay(&self) -> SimulationTime

Calculate the simulated delay until this CPU is ready to run again.
