# [−][src]Struct test::bench::Bencher

    pub struct Bencher {
        pub bytes: u64,
        // some fields omitted
    }

🔬 This is a nightly-only experimental API. (`test`)

Manager of the benchmarking runs.

This is fed into functions marked with `#[bench]` to allow for set-up & tear-down before running a piece of code repeatedly via a call to `iter`.

## Fields

`bytes: u64`
