# [−][src]Trait rayon::iter::plumbing::Reducer

    pub trait Reducer<Result> {
        fn reduce(self, left: Result, right: Result) -> Result;
    }

The reducer is the final step of a `Consumer` -- after a consumer has been split into two parts, and each of those parts has been fully processed, we are left with two results. The reducer is then used to combine those two results into one. See the `plumbing` README for further details.

## Required methods

### `fn reduce(self, left: Result, right: Result) -> Result`

Reduce two final results into one; this is executed after a split.

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
