Struct ReduceWindow 

Source 
pub struct ReduceWindow<T, RIn, ROut> {
    pub keys: Vec<u64>,
    pub input: ProxyBridge<T, RIn>,
    pub output: ProxyBridge<T, ROut>,
}
Expand description

One window of a retire’s changed keys: a bounded, hash-contiguous snip the backend sizes.

The window has the input (old and new) and output histories, restricted to the window’s keys.

Fields§

§keys: Vec<u64>

The window’s key hashes: a contiguous, ascending slice of the retire’s changed keys.

§input: ProxyBridge<T, RIn>

Input presentation for keys, sorted & consolidated by ((key_hash, value_id), time).

§output: ProxyBridge<T, ROut>

Output-history presentation for keys, same ordering.
