Configuration for native histograms.

Implementations§

Source§

impl NativeHistogramConfig

Source

pub fn new( bucket_factor: f64, max_buckets: u32, zero_threshold: f64, ) -> Result<Self, &'static str>

Creates a new native histogram configuration.

§Arguments
  • bucket_factor - The base for exponential buckets (must be > 1.0)
  • max_buckets - Maximum number of buckets to limit memory usage
  • zero_threshold - Threshold for considering values as zero (must be >= 0.0)
§Returns

A new configuration, or an error if parameters are invalid.

§Errors

Returns an error if bucket_factor is not greater than 1.0, max_buckets is 0, or zero_threshold is negative.

Source

pub fn bucket_factor(&self) -> f64

Returns the bucket factor.

Source

pub fn max_buckets(&self) -> u32

Returns the maximum number of buckets.

Source

pub fn zero_threshold(&self) -> f64

Returns the zero threshold.
