Struct ThinningStats 

pub struct ThinningStats {
    pub input_count: usize,
    pub kept_count: usize,
    pub reduction_ratio: f64,
}

Summary statistics for a single thinning invocation.

Fields

input_count: usize

Number of points in the input cloud.

kept_count: usize

Number of points in the output cloud after thinning.

reduction_ratio: f64

Fraction of input points discarded, in [0, 1]. Defined as 1 - kept_count / input_count; zero when input_count == 0.

Implementations

impl ThinningStats

pub fn new(input_count: usize, kept_count: usize) -> Self

Construct a ThinningStats from the input/output cardinalities, computing the reduction ratio.

reduction_ratio is 0.0 when input_count == 0 to avoid a division-by-zero, and is otherwise clamped to [0, 1] by construction (because kept_count <= input_count for every operator in this module).

Trait Implementations

impl Clone for ThinningStats

fn clone(&self) -> ThinningStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ThinningStats

impl Debug for ThinningStats

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

Formats the value using the given formatter.

impl Default for ThinningStats

fn default() -> ThinningStats

Returns the “default value” for a type.
