Struct Config 

pub struct Config {
    pub max_num_bins: u32,
    pub gamma: f64,
    pub offset: i32,
    /* private fields */
}

The configuration struct for constructing a DDSketch

Fields

max_num_bins: u32

gamma: f64

offset: i32

Implementations

impl Config

pub fn new(alpha: f64, max_num_bins: u32, min_value: f64) -> Self

Construct a new Config struct with specific parameters. If you are unsure of how to configure this, the defaults method constructs a Config with built-in defaults.

max_num_bins is the max number of bins the DDSketch will grow to, in steps of 128 bins.

pub fn defaults() -> Self

Return a Config using built-in default settings

pub fn key(&self, v: f64) -> i32

pub fn value(&self, key: i32) -> f64

pub fn log_gamma(&self, value: f64) -> f64

pub fn pow_gamma(&self, key: i32) -> f64

pub fn min_possible(&self) -> f64

Trait Implementations

impl Archive for Config

where u32: Archive, f64: Archive, i32: Archive,

const COPY_OPTIMIZATION: CopyOptimization<Self>

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

type Archived = ArchivedConfig

The archived representation of this type.

type Resolver = ConfigResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for Config

fn clone(&self) -> Config

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Config

impl Debug for Config

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

Formats the value using the given formatter.

impl Default for Config

fn default() -> Self

Returns the “default value” for a type.

impl<__D: Fallible + ?Sized> Deserialize<Config, __D> for Archived<Config>

where u32: Archive, <u32 as Archive>::Archived: Deserialize<u32, __D>, f64: Archive, <f64 as Archive>::Archived: Deserialize<f64, __D>, i32: Archive, <i32 as Archive>::Archived: Deserialize<i32, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<Config, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl PartialEq for Config

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

Equality operator ==.

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

Inequality operator !=.

impl<__S: Fallible + ?Sized> Serialize<__S> for Config

where u32: Serialize<__S>, f64: Serialize<__S>, i32: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
