Struct ExponentialAggregationStrategy 

pub struct ExponentialAggregationStrategy { /* private fields */ }

Exponential bucketing strategy using the histogram crate.

This uses 976 buckets and supports values from 0 to u64::MAX. Values greater than u64::MAX are truncated to u64::MAX. Scaling factor for converting floating point values to integers for histogram bucketing. 2^10 = 1024, providing 3 decimal places of precision.

Uses exponential bucketing with configurable precision. Default configuration uses 4-bit mantissa precision (16 buckets per order of magnitude, ~6.25% error).

Implementations

impl ExponentialAggregationStrategy

pub fn new() -> Self

Create a new exponential aggregation strategy with default configuration.
