# [−][src]Struct test::test::MetricMap

    pub struct MetricMap(_);

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

## Implementations

### `impl MetricMap`[src]

#### `pub fn new() -> MetricMap`[src]

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

#### `pub fn insert_metric(&mut self, name: &str, value: f64, noise: f64)`[src]

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

Insert a named `value` (+/- `noise`) metric into the map. The value must be non-negative. The `noise` indicates the uncertainty of the metric, which doubles as the "noise range" of acceptable pairwise-regressions on this named value, when comparing from one metric to the next using `compare_to_old`.

If `noise` is positive, then it means this metric is of a value you want to see grow smaller, so a change larger than `noise` in the positive direction represents a regression.

If `noise` is negative, then it means this metric is of a value you want to see grow larger, so a change larger than `noise` in the negative direction represents a regression.
