Struct async_singleflight::Group [−][src]
Group represents a class of work and creates a space in which units of work can be executed with duplicate suppression.
Implementations
impl<T> Group<T>
[src]
pub fn new() -> Group<T>
[src]
Create a new Group to do work with.
pub async fn work<Fut>(
&self,
key: &str,
func: impl Fn() -> Fut
) -> Arc<Result<T>> where
Fut: Future<Output = Result<T>>,
[src]
&self,
key: &str,
func: impl Fn() -> Fut
) -> Arc<Result<T>> where
Fut: Future<Output = Result<T>>,
Execute and return the value for a given function, making sure that only one operation is in-flight at a given moment. If a duplicate call comes in, that caller will wait until the original call completes and return the same value.
