# [−][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`
🔬 This is a nightly-only experimental API. (`test`)

## Methods

### `impl Bencher`[src]

#### `pub fn iter<T, F>(&mut self, inner: F) where
F: FnMut() -> T,` [src]

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

Callback for benchmark functions to run in their body.

#### `pub fn bench<F>(&mut self, f: F) -> Option<Summary> where
F: FnMut(&mut Bencher),` [src]

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