Struct TokioYield 

pub struct TokioYield;

Available on crate feature async-tokio only.

An implementation of SleepProvider using Tokio’s yield.

This strategy avoids timer-based delays by yielding to the scheduler immediately, which can improve responsiveness in low-concurrency scenarios.

However, it comes at the cost of more frequent rescheduling, which can result in tighter polling loops and increased CPU usage under load. In highly concurrent cases, a timer-based sleep (e.g., TokioSleep) is often more efficient due to reduced scheduler churn.

Trait Implementations

impl SleepProvider for TokioYield

Available on crate features async-tokio or async-smol only.

type Sleep = Pin<Box<dyn Future<Output = ()> + Send>>

Available on crate feature futures only.

Tokio’s yield_now() returns a private future type, so we must use a boxed dyn Future to abstract over it.

fn sleep_for(_dur: Duration) -> Self::Sleep

Available on crate feature futures only.
