Struct leaky_bucket::Acquire
source · pub struct Acquire<'a>(_);
Expand description
The future associated with acquiring permits from a rate limiter using
RateLimiter::acquire
.
Implementations§
source§impl Acquire<'_>
impl Acquire<'_>
sourcepub fn is_core(&self) -> bool
pub fn is_core(&self) -> bool
Test if this acquire task is currently coordinating the rate limiter.
Examples
use leaky_bucket::RateLimiter;
use std::future::Future;
use std::sync::Arc;
use std::task::Context;
struct Waker;
let limiter = RateLimiter::builder().build();
let waker = Arc::new(Waker).into();
let mut cx = Context::from_waker(&waker);
let a1 = limiter.acquire(1);
tokio::pin!(a1);
assert!(!a1.is_core());
assert!(a1.as_mut().poll(&mut cx).is_pending());
assert!(a1.is_core());
a1.as_mut().await;
// After completion this is no longer a core.
assert!(!a1.is_core());
