Struct async_singleflight::Group[][src]

pub struct Group<T> { /* fields omitted */ }

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]

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.
