Struct SigFigBucketizer

pub struct SigFigBucketizer { /* private fields */ }

SigFigBucketizer provides methods for computing bucket boundaries and the bucket to which a value belongs.

Implementations

impl SigFigBucketizer

pub const fn new(sig_figs: i32) -> Self

Create a new SigFigBucketizer.

Panics

If sig_figs < 1 or sig_figs > 4, this function will panic.

pub fn boundary_for(&self, b: i32) -> f64

Compute the value all observations in bucket b round to.

Panics

If the boundary b is negative.

pub fn bucket_for(&self, x: f64) -> usize

Compute the bucket for the value.

Panics

If the observation x is negative.

pub fn iter(&self) -> impl Iterator<Item = f64> + '_

Iterate over the value assigned to each bucket.

Trait Implementations

impl Clone for SigFigBucketizer

fn clone(&self) -> SigFigBucketizer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SigFigBucketizer

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

Formats the value using the given formatter.

impl PartialEq for SigFigBucketizer

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