Struct ExponentialBuckets 

#[non_exhaustive]
pub struct ExponentialBuckets {
    pub num_finite_buckets: i32,
    pub growth_factor: f64,
    pub scale: f64,
    /* private fields */
}

Describing buckets with exponentially growing width.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

num_finite_buckets: i32

The number of finite buckets. With the underflow and overflow buckets, the total number of buckets is num_finite_buckets + 2. See comments on bucket_options for details.

growth_factor: f64

The i’th exponential bucket covers the interval [scale * growth_factor^(i-1), scale * growth_factor^i) where i ranges from 1 to num_finite_buckets inclusive. Must be larger than 1.0.

scale: f64

The i’th exponential bucket covers the interval [scale * growth_factor^(i-1), scale * growth_factor^i) where i ranges from 1 to num_finite_buckets inclusive. Must be > 0.

Implementations

impl ExponentialBuckets

pub fn new() -> Self

pub fn set_num_finite_buckets<T: Into<i32>>(self, v: T) -> Self

Sets the value of num_finite_buckets.

Example

let x = ExponentialBuckets::new().set_num_finite_buckets(42);

pub fn set_growth_factor<T: Into<f64>>(self, v: T) -> Self

Sets the value of growth_factor.

Example

let x = ExponentialBuckets::new().set_growth_factor(42.0);

pub fn set_scale<T: Into<f64>>(self, v: T) -> Self

Sets the value of scale.

Example

let x = ExponentialBuckets::new().set_scale(42.0);

Trait Implementations

impl Clone for ExponentialBuckets

fn clone(&self) -> ExponentialBuckets

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExponentialBuckets

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

Formats the value using the given formatter.

impl Default for ExponentialBuckets

fn default() -> ExponentialBuckets

Returns the “default value” for a type.

impl Message for ExponentialBuckets

fn typename() -> &'static str

The typename of this message.

impl PartialEq for ExponentialBuckets

fn eq(&self, other: &ExponentialBuckets) -> 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.
