Struct LinearEstimator 

pub struct LinearEstimator {
    pub name: String,
    pub bytes_per_element: usize,
    pub fixed_overhead: usize,
    pub auxiliary_per_element: usize,
}

A linear memory estimator (bytes_per_element * count + overhead).

Fields

name: String

Name of this estimator.

bytes_per_element: usize

Bytes per element.

fixed_overhead: usize

Fixed overhead bytes.

auxiliary_per_element: usize

Auxiliary bytes per element.

Implementations

impl LinearEstimator

pub fn new(name: impl Into<String>, bytes_per_element: usize) -> Self

Creates a new linear estimator.

pub fn with_overhead(self, bytes: usize) -> Self

Builder method to set fixed overhead.

pub fn with_auxiliary(self, bytes_per_element: usize) -> Self

Builder method to set auxiliary bytes per element.
