FnSink

grafos_stream::sink

Struct FnSink 

Source 
pub struct FnSink<T, F: FnMut(T)> { /* private fields */ }
Expand description

Sink that wraps a closure.

§Example

use grafos_stream::sink::FnSink;
use grafos_stream::stage::Sink;

let mut total = 0u64;
{
    let mut sink = FnSink::new(|x: u32| { total += x as u64; });
    sink.accept(10).unwrap();
    sink.accept(20).unwrap();
}
assert_eq!(total, 30);
