Enum HistogramScale

#[non_exhaustive]
pub enum HistogramScale {
    Linear,
    Log,
}

Available on tokio_unstable and crate feature rt only.

Whether the histogram used to aggregate a metric uses a linear or logarithmic scale.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Linear

Linear bucket scale

Log

Logarithmic bucket scale

Trait Implementations

impl Clone for HistogramScale

fn clone(&self) -> HistogramScale

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HistogramScale

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for HistogramScale

fn eq(&self, other: &HistogramScale) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
